The ever pretty Kristen Bell was enjoying a bike ride in Los Angeles, the cameraman was trying to get a nice picture of her ass while she was riding the bike and actually managed to get a better shot when she took a break to say hello to this pooch. We don’t get to see too many ass cracks so I felt it was worth a feature although I am not expecting it to score highly amongst regulars unless that are ass crack fans.

It seems all the hottest celebrity asses are being captured whilst they are wearing tight jeans at the moment, here we see Hilary Swank out shopping in a pair. I am not complaining about the jeans, as far as I am concerned a tight cute ass is a tight cute ass whether it be covered in a nice bikini or a skin tight pair of jeans.

Myleene Klass is looking pretty damn hot as she walks down the street wearing a rather tight pair of jeans and an orange vest. At first I thought she looked a little too skinny and I would have said she could do with putting on a pounds but when the camera gets a shot of a rear everything is just fine, great ass Myleene.

The love was flowing at an after dinner awards ceremony in London for Hollyoaks actress Stephanie Davies, she was hugging and kissing almost everyone that passed by including a male model who was lucky enough to be pounced on.

Wrapping her legs around his thighs and planting a smacker on his lips Stephanie probably revealed a little more than she would have liked to as her dress took a ride north revealing what appeared to be her naked ass. Later images of Stephanie getting into a car and opening her legs showed that she was actually wearing a thong panty.

Cameron Diaz has always been one of my favourite celebs, not just for her gorgeous looks and infectious smile but that tight body of her too. I featured Cameron Diaz a few months back wearing a bikini and looking hot. Here we see Cameron leaving a gym in Santa Monica wearing a pair of tight leggings and confirming just why I still have the hots for her.

This girls seems to be enjoying more than her fair share of holidays in the sun but who can blame her, if you live in the UK at the moment you cannot have failed to notice we are having more than a fair share of rain and grey skies at the moment. Rihanna however has finished filming Battleship she has done her duty appearing at the premiers and now it is time out in Hawaii.

Now I know the second image below doesn’t show Rihannas  booty off half as well as the the first image that you see above but can you even begin to imagine how great the view must be from the front? I wonder if the front is tight into the groin or do you reckon they might have been a little loose and gaping?

The next two images were taken on the same day a few hours later, I guess Rihanna is either unhappy about being pictured wearing the same bikini twice in a day or she simply doesn’t like the feel of the wet material against her fine toosh. I wonder if Rihanna is on an extended vacation and if so what are the chances we shall see a few more outfits later in the week?

So what do we prefer folks, the earlier in the day black bikini or the snazzy blue one? My personal preference has to be for the blue one, simply for the fact it looks one size smaller and definitely tighter on that sexy booty.

Nice nails Rihanna but do tell me, did we just miss a little scratch of the cheek or was it a pluck it out of the crack moment?

Maybe not as hot as the earlier pictures we posted of Imogen Thomas when she was revealing her naked ass in what looked like a staged upskirt but still very appealing all the same. Here we have two more asstastic images of Imogen in her rather tight lycra leggings.

The first and second image should be the other way around really, the first image shows Imogen bending over to pick up the keys to her car which she dropped, I am surprised there was not a queue forming behind her.

I love it when women wear lycra bottoms that are just slightly too tight and over stretched, it doesn’t matter if you wear black panties underneath, we can still see your thong Imogen. I am just wondering as well how hard this workout was for Imogen as I can’t see any damp sweat patches!!

You are virtually guaranteed a great ass shot when it is a female tennis star in action, no exceptions here then with a great upskirt sport panties flash from Caroline Wozniacki. This picture was taken at a charity event, just enough running about to ensure that the panties hug nice and tight to her rounded ass.

Can you ever get enough of Miley Cyrus? Here we see her out jogging wearing our friend; the spandex leggings. I wonder if she was hot and sweaty under these? I can’t see any sweat patches maybe she remembered to wear her panties this time. For those that would love to see a little more of Miley have you seen the upskirt pictures captured while she wasn’t wearing any panties? They are available to view at Celebrity Porn XXX and their Miley Cyrus Vagina post.

Home and Away star Indiana Evans shows us a glimpse of what we can expect as she is pictured here in her nice tight bikini on set for her role as Emma’ Robinson in the soon to be released film Blue Lagoon. I don’t know if the film is going to be any good, however these images have it sold as far as I am concerned.

I am pretty sure we are going to be seeing a lot more of this actress in the months and years ahead, a star in the making possibly? – Almost guaranteed with a looks and a tight butt like this wouldn’t you agree?

I love how the sea water has made her bikini cling to her cheeks and hug the crack line like this and they are string fastened too!! Indiana sure does have a fit ass, bordering on spectacular I would say.

Angela Simmons makes her second appearance here on Celebrity Ass. The first time around we were treated to a nice full figure booty shot as she strolled along a beach in her bikini, this time we get to see what Angela wears under her black jeans, a very nice and rather skimpy g-string by the looks of things, almost a whale tail but not quite, still a very nice ass shot.

Laura Prepon was grabbing a coffee in LA recently when these pictures were taken of her showing off her ass, why else would she be wearing such seductive leggings? Not bad for the actress who plays Donna Pinciotti in the long running American sitcom That ’70s Show. As the sun beats down on her celebrity ass in image two, you can clearly see that Laura is wearing big style panties under those leggings and is that a hint of cellulite that we see? Okay ladies it is only natural and natural is good right?
