Olivia Wilde's baby bump is growing bigger by the day ... and what better way to dress it than in an Yves Saint Laurent tee?!

The mom-to-be stopped for some java (decaf, we assume) in Venice, on Thursday, along with her adorable pooch, Paco.

The actress has about three months to go before she delivers a baby boy -- her first child with fiance Jason Sudeikis. Once they welcome the little one, it'll be back to work for Wilde -- she'll be staring in and producing psychological thriller Meadowland in July!

Katy Perry sure knows how to vamp it up!

The pop goddess dons a Cleopatra costume and silver body paint in the new music video for her single "Dark Horse," featuring Juicy J, from her album PRISM.

Oh, and she has the power to turn bad boys to sand! Check it out ...

Hey, Khloe, what's up?!

Mrs. Kardashian was NOT having it on Thursday as she filmed a scene for the family's reality show with Scott Disick. KK gave the middle finger when we asked if she'd be visiting Lamar any time soon.

Seriously, we can understand if Khloe's in a less-than-great mood after ex-hubby Lamar Odom is now officially out of the picture, having jetted off to Spain to join a basketball league there. Though ... the baller was photographed wearing his wedding ring, so what gives?

Less than a week after Christina Aguilera announced her engagement to long-time boyfriend Matthew Rutler, a report now claims the Grammy-winning singer is pregnant, according to a new report by Us Weekly.

Aguilera, 33, has been dating Rutler, 28, since the two met on the set of Xtina's 2010 film Burlesque.

Christina has one child, Max, age 6, with ex-husband Jordan Bratman. The pair split in the fall of 2010 just before Aguilera started dating Matt in November. Bratman and Aguilera share custody of Max.

The pop star is on leave from seasons 6 of The Voice after taking off season 4 as well, when Shakira will fill in.

Is North West getting another cousin?

Kourtney Kardashian grabbed lunch at Marmalade Cafe in Calabasas today, and the reality star looked like she might have been hiding a baby bump under her loose t-shirt.

Could she and Scott Disick be expecting a sibling for Mason and Penelope?

The brunette beauty and her sisters Kim and Kourtney just launched a kids clothing line, so it would be perfect timing! Not only that, but the mother-of-two just bought a brand new, bigger home in Calabasas, so there's more than enough room for another tot!

How does she stay so skinny?!

Selena Gomez must have had a craving for bad Mexican food, because she stopped by Taco Bell in Hollywood today for some grub!

The actress made sure to look super cute on her fast food run in a romper and heels, and we guess if you're going to eat gross food, you might as well look adorable doing it!

Rehab seems to have kicked her Justin Bieber addiction, but not her addiction to tacos!

Hide your daughters, Harry Styles is coming to America!

Highlighting his baby blues with a knit cap, the sexy One Directioner looked ready to take the states by storm as he touched down at LAX on Thursday.

For his cross-continent flight, the 19-year-old looked comfy in black jeans, a black hoodie and suede ankle boots -- but even dressed down he looks like a total Baldwin!

On Monday, Harry was in fine form when he turned up at the Serpentine in Kensington Gardens for Burberry Prorsum's runway show during London Fashion week. While we loved seeing the British stud get his fashion fix on, we had to take note of the fact that the 19-year-old was without his rumored girlfriend, Kendall Jenner, who had been was spotted front row at TopShop Unique's show the day prior.

Despite never officially going public with their romance, the rumored couple had been photographed together several times in both New York and Los Angeles. Since Kendall and Harry weren't photographed together this week even though they were both in London at the same time, we have to wonder if their teenage romance is over. It certainly appears that way to us!

If heart breaker Harry is single yet again that means there's plenty more of the mop-topped Brit for the rest of us. Yay!

Uhhh sorry BritBrit, but we are not liking the new look!

Pop star Britney Spears showed off her new brunette hairstyle while making a post-gym stop at Michael's craft store in Calabasas on Thursday. And we are a little baffled by the normally blonde star's color choice!

Dressed down in her usual off-duty gear, Britney was looking anything but an A-lister for her errand-filled afternoon.

Here are some hair commandments that we really don't think should be messed with: If your name ends in "Kardashian," thou shalt forever be brunette (stop with this ombre and blonde madness, it does your family no justice!). Secondly: if you are a pop icon whose name is Britney Spears, thou shalt be a blonde.

There is just something off kilter with the world when they flip flop their signature hair colors -- and we just don't like it.

This is the first time we've gotten a good look at the reddish brown mane, however we did see a pic earlier in the week of the darker style. On Tuesday, friend Nicole Richie Instagramed a pic of herself and the newly brunette singer while on stage at Brit's show in Las Vegas, but this is the first time we've seen her out and about with the new 'do. The 32-year-old reality star-turned fashion designer was seen smiling as the "Toxic" singer pulled her on stage for a sexed-up performance of "Freak Show."
