Taylor Armstrong, Camille Grammer, Kathy Hilton and Kyle Richards seem to defy the aging process!

The Real Housewives of Beverly Hills stars sizzled on the blue carpet for Andy Cohen's book release party at LA's SUR Lounge for "Most Talkative: Stories From The Front Lines Of Pop Culture."

Bravo's EVP is lucky to have this kind of support from so many beautiful ladies!

What WE expect is for these ladies to look perfect ... and they certainly do!

Jennifer Lopez, Cameron Diaz and Brooklyn Decker were decked out to the nines while they worked the red carpet at the premiere for their new movie What To Expect When You're Expecting.

We have to admit that JLo really put Cam's dress to shame. The sexy 42-year-old Latina sizzled in a floor length and flowy Maria Lucia Hohan Gown. She paired her dress with Sergio Rossi shoes and jewelry by Jacqueline Nerguizian.

Ms. Diaz played it safe in a short and semi-sheer black knitted dress ... showing off her incredibly sexy bod. Cute, but a little too understated if you ask us.

Brooklyn Decker chose a Giambatista Valli dress and jewelry by Blue Nile jewels. The perfect choice, indeed!

See all of the stars who hit the red carpet in our gallery below.

Who better than blonde bombshell Scarlett Johansson to re-enact Janet Leigh's infamous Psycho shower scene?

The Avengers star looked nearly identical to the 60s screen siren in a tight yellow blouse, tan pencil skirt, sky high pumps and a short blonde wig as she strolled through the set of the upcoming flick Alfred Hitchcock and the Making of Psycho while carrying a big umbrella, on Monday afternoon.

The 27-year-old beauty stars alongside Hollywood heavyweights Helen Mirren as Hitchcock's wife Alma Reville, Jessica Biel as Johansson's onscreen sister Vera Miles, and Sir Anthony Hopkins will play the title role.

The film centers on the complicated relationship between Hitchcock and his wife, as well as offering a first hand look at one of the most iconic horror flicks in movie history.

Britney Spears has definitely got the X-Factor!

After making it official that she's set to join the second season of Simon Cowell's reality competition show as a judge, Miss B hopped on a golf cart and headed straight to ABC Kitchen to celebrate over dinner with fiance, Jason Trawick!

The Princess of Pop looked better than ever in a skintight purple dress and bright blonde locks, after changing out of the sexy white ensemble she wore at the FOX Upfronts, on Monday.

Spears, along with former Disney star Demi Lovato, will be taking over for Paula Abdul and Nicole Scherzinger, where they'll sit with Simon Cowell and record producer L.A. Reid at the judges table.

The "I Wanna Go" singer, who is reputedly making around $15 million for the gig, exclaimed after the big announcement: "I'm so excited about this whole experience. It's going to be so much fun and so different from anything I've ever done. I'm ready to find a true star."

Lovato added, "I am totally stoked to be here. I'm excited to represent my generation and I'm ready to find the winner."

With Simon and Demi by Brit's side, it's sure to be a sensational season packed with plenty of drama!

Katherine Heigl and Josh Kelley are the proud parents of a new baby girl!

The couple welcomed Adalaide Marie Hope this month, who was was adopted from Louisiana, according to Life & Style. She joins the couple's first adopted daughter, 3-year-old Naleigh, who is a special needs child from South Korea.

Heigel recently revealed of her decision to adopt: “Josh and I started talking about [adoption] before we were even engaged. My sister Meg is Korean, and my parents adopted her three years before I was born. I wanted my own family to resemble the one I came from, so I always knew I wanted to adopt from Korea.”

Kelly and Heigel took their baby out for the first time on Mother's Day, but they kept her hidden under a blanket. We can't wait to see her face!

A overly dolled up Kim Kardashian met with E! producers today in Beverly Hills, and since both parties have already inked a $40 million deal to renew Keeping Up With The Kardashians for three more seasons, it seems like they're either discussing possible story lines OR there's going to be a whole new show in the works!

Could Kim already be thinking about planning a wedding and a subsequent wedding episode? Kanye has rapped about putting her in a white dress, but he still hasn't proposed, but with this media hungry couple, we think anything is possible!

P.S. Is it just us, or is her hair a bit um, devilish in this shot?

See Cameron Diaz, Jennifer Lopez, Elizabeth Banks, Chace Crawford, Brooklyn Decker, Anna Kendrick, Matthew Morrison, Dennis Quaid and Chris Rock walk the red carpet LIVE!

What to Expect When You're Expecting hits theaters everywhere May 18th!

Ellen and Portia make quite the cute couple!

The pair were spotted in Malibu yesterday, showing some PDA while walking on the beach in Malibu.

The ladies weren't in your traditional beach attire due to the overcast weather but that didn't stop them from enjoying the outdoors. They purchased Brad Pitt's Malibu beachfront home at the end of 2011 for a reported $12 million -- $2 million less than the asking price.

With that type of deal, life's a beach, indeed!
