Who's that girl?! Why it's Jennifer Aniston of course! The actress went for an incognito look when she wore a fedora, sunglasses and scarf to a Los Angeles spa on Friday afternoon. Disguise or no disguise -- we can spot that signature square jaw anywhere!

While we hadn't seen Jen and fiance Justin Theroux for awhile, we spotted the Horrible Bosses 2 star and her main man Christmas tree shopping yesterday and the today the star's engagement ring is still front and center. So it looks like all is well in love land!

Pregnancy rumors have been swirling for months. Back in September Us Weekly reported that Aniston and Theroux were expecting their first child together, but since they ran that as a cover story, there haven't been any further mentions of the 44-year-old actress having a bun in the oven -- and Jen doesn't look like she has a baby bump to us!

Recently, People.com reported the couple has put their plans for a wedding and kids on hold, however the story was subsequently taken down. A source told the mag, "She had included her friends and seemed excited [about the process]," but then decided "she needed to focus on work." The insider added, "There was a lot of baby talk in the past, but she is not focused on it. She's aware her age makes it more difficult. Her attitude is, 'If it happens, great, but if it doesn't, it wasn't meant to be.'"

Let's hope these are just rumors -- we like the two of them together!

Beyonce and Jay Z are just four days into their 22-day vegan, plant-based diet, but have already tried some of LA's better-known healthy restaurants. On Friday, Beyonce, who looked like she was wearing a faux cowhide sweatshirt, and her main man lunched at Crossroads Kitchen, a trendy vegetarian restaurant in Los Angeles.

And it looks like the twosome is pretty serious about her new diet -- Bey and Jay have been doing a health food tour of the city of Angels this week. The duo started their spree at Real Food Daily in West Hollywood on Tuesday; went to Cafe Gratitude on Wednesday and then we spotted them at Native Foods in Westwood Thursday!

"On December 3rd, one day before my 44th birthday, I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based!" Jay Z wrote on his website, Life + Times. "This all began a few months back when a good friend and vegan challenged me to embrace a 'plant-based breakfast' everyday. It was surprisingly easier on me than I thought..."??

The 44-year-old wrote rapper also wrote that his lady love would be committing to the food challenge, adding, "P.S. B is also joining me."

Jay Z and Bey were in Los Angeles for B's star-studded concert at Staples Center.

We guess if you are going to go vegan -- LA is probably the best place to start. We love our kale and quinoa here!

Her bun in the oven is starting to get big!

Olivia Wilde stepped out in L.A. today wearing spandex pants, a t-shirt, and a leather jacket, and it seems her baby belly has finally popped!

The actress, who is expecting her first child with fiance Jason Sudekis, has reportedly been practicing Pilates throughout her pregnancy, which may explain why she's in such great shape everywhere else!

We wonder when the brunette beauty and her SNL funny man are going to tie the knot?

She could go the Jessica Simpson route and put the baby carriage before marriage, or she could pull a Jennifer Love Hewitt and have a secret ceremony before welcoming her bundle of joy!

When did they morph into such hipsters?!

Anne Hathaway and husband Adam Schulman dressed for the chilly L.A. temperatures to grab brunch at Hugo's in West Hollywood today, and we never noticed this before, but the couple looks a lot like brother and sister!

The Oscar winner might not realize it, but the real life von Trapp family preferred her over Carrie Underwood to star in The Sound of Music Live!.

"[Our family has] had the conversations of who could play this role better and it was Anne Hathaway for example. Here's someone who just won an Oscar for a similar situation. She was able to act and sing [in Les Miserables]," Maria von Trapp's great grandson told ABC News.

That's quite the feather in her cap!

On Thursday Gwen Stefani stopped by the home of bandmate/former beau Tony Kanal, and after that the two went to lunch in West Hollywood. Gwen showed off her growing baby bump in a tight black top and a chic white jacket, and she wore her signature red lipstick. She hasn't stepped out in one questionable outfit since the news of her pregnancy broke ... she always looks amazing!

Kanal and his wife Erin welcomed their second daughter together, Saffron Rose Kiran Kanal, two weeks ago, so it appears as though auntie Gwen got some facetime with the newest member of the No Doubt family.

On Friday afternoon Amanda Bynes went to an outpatient rehab in Thousand Oaks, California with her mom Lynn, and after that the 27-year-old actress went to a nearby medical imaging center.

Amanda kept her look simple in jeans, sneakers and a black sweater, and she accessorized with a Chanel bag, a gold necklace and funky shades. Yesterday X17 snapped Amanda for the first time since she left rehab last week, and she wore a very similar outfit with a sweatshirt that said "Gangsta Love." She hasn't exactly been smiling since we've seen her, but it's good to see that she's letting her sense of humor show with her wardrobe...

"I am doing very well. I'm doing great, it's been five days since I got out of rehab," she told In Touch yesterday. Bynes was discharged and placed in the care and supervision of her mother, and she will stay with her family while still continuing to go to outpatient counseling. Bynes is set to appear in court on January 7 regarding her DUI case, but right now it looks like the starlet and her family are taking things one step at a time.

So which one is it?!

Drew Barrymore kept the guessing game going as to the gender of her unborn child with a pink and blue manicure that she shared on Instagram yesterday.

We're just speculating, but since her ring finger is blue, we're gonna guess she might be having a boy!

"Celebrated a fun new partnership last night between @flowerbeauty and @olivejune. Thanks to @gibsontuttle for hosting us at her lovely salon and @aka_katt for the rad manicure. #nailedit #flowerbeauty," she captioned the snapshot.

Flowerbeauty is the married star's cosmetic line, and Olive and June is an upscale nail salon in Beverly Hills owned by Sarah Gibson Tuttle.

Daughter Olive must be happy to be getting a sibling!

We can't believe she hasn't popped yet ... she's due any day now!

Rachel Zoe and hubby Rodger Berman went to the doctor on Thursday afternoon, and the proud parents were all smiles after their pre-natal checkup. Rachel is reportedly having another son, and the due date was never officially announced, but we're guessing that was one of her last appointments before heading in to the delivery room!

And speaking of that, here's to hoping her second experience with childbirth is a little easier than the first -- the celeb stylist was in labor for 16 hours with son Skyler back in 2011!
