Rosie Huntington-Whiteley hit the gym in the valley on Wednesday, and the Victoria's Secret hottie flashed us a peek at her tight and toned tummy in a sports bra and spandex.

And when she's not slaving away to keep her model bod looking picture perfect in lingerie, she's promoting her own undergarments! Her line of intimates with Marks & Spencer has been out for a year, so naturally she's created an anniversary collection with the U.K. retailer!

“I can’t quite believe it’s been a whole year since the Rosie for Autograph launch, it’s gone so fast!” Rosie told Vogue U.K.. "For my one year anniversary collection, I’m loving the new shapes and, as well as including my signature soft colors, I’ve experimented with a darker, richer palette perfect for the autumn season."

Since its launch, the range has become the fastest selling underwear in the store's history ... looks like Ms. H-W is well on her way to building a fashion empire!

Leah Remini has filed a missing persons report with the Los Angeles Police Department for Scientology leader David Miscavige's wife Shelly, who hasn't been seen in public for more than 6 years.

"Our missing persons unit informed us that Leah Remini did file a missing person report on a Shelly Miscavige," a spokesperson for the LAPD said. "That is all we are going to say at this time."

The Church has previously stated that Shelly is not missing, and veteran Scientology reporter/former Village Voice editor Tony Ortega claims she's living at a private Scientology compound outside Los Angeles. However, things could get interesting, because now that authorities are involved, the Church "may be forced to produce Shelly Miscavige, or if they don't, the police might just decide to go up there and look for themselves," according to The Atlantic.

Remini made headlines last month when she left the Church of Scientology, and last week she revealed that she's writing a tell-all book! "It will include my experiences, everything that's taboo to talk about," Leah told Us Weekly at the 15th annual DesignCare event in Malibu last weekend. "It's a time of change. I think the fact that my family has taken a stance and we are on a united front says a lot."

Looks like the mom-on-the-go is having a little alone time! Spotted without her favorite accessory -- her kids -- Jennifer Garner was snapped after having lunch in Brentwood, Calif., on Wednesday. Normally going for function over fashion, the laid back mother of three opted for a girly Theory dress for her lunch date. After her meal, the 41-year-old was all smiles as she chatted on the phone while walking to her car.

This summer, the 30 Going on 30 actress has been snapped toting around her adorable tots around town. Earlier this week, Jen ran back-to-school errands with Violet and brought a tutu-wearing Seraphina to ballet class.

Recently, Ben Affleck's lady love has been sparking pregnancy rumors with her loose clothing choices. Does Jen have bun No. 4 in the oven? We can't wait to find out!

Baby on the way or no baby on the way, Mrs. Affleck reteams with her Ghosts of Girlfriends Past actor Matthew McConaughey in the drama Dallas Buyers Club, due out on December 6.

Young love doesn't last forever! British actors Lily Collins and Jamie Campbell Bower have broken up, reports Us Weekly. But you wouldn't know that from these photos! Just a day before announcing the split, Lily looked stunning for an appearance on Good Morning America in New York City on Wednesday. The couple has been dating since July 2012 and met while shooting the fantasy flick, The Mortal Instruments: City of Bones, which hits theaters Aug. 21. A source tells Us Weekly, "They remain very good friends."

Nothing makes a girl look her best like a break up! Lily seems to be taking the rift in stride, strutting her stuff in a Valentino frock and Jimmy Choo heels through the city streets.

However, things could be getting a little awkward for the former couple in the coming weeks -- the twosome are currently promoting their new film and are on a nationwide press tour together, which includes appearances, interviews and more. Despite being in close quarters, the source also added, "They've been really good about doing the press tour together for their movie. They were able to stay friendly." Let's just hope that neither one of them brings around a new paramour until the press tour is over!

As the old saying goes, there are plenty of fish and the sea and it seems as if neither Lily or Jamie have had any problems in their past catching anything. Lily previously dated her Abduction costar Taylor Lautner from November 2010 to September 2011, and also had a romance slam dunk with Zac Efron for three months in 2012. Campbell Bower is no slouch himself; the Twilight Saga: Breaking Dawn star was previously engaged to his Harry Potter and the Deathly Hallows: Part 1 costar Bonnie Wright.

If Lily keeps looking like this -- she is sure to have a new man in no time!

It's important to make sure everything is progressing nicely!

Jack Osbourne's pregnant wife Lisa Stelly headed to a doctor's appointment in Beverly Hills yesterday with daughter Pearl, and even though news of her pregnancy broke just yesterday, she's already sporting a noticeable baby bump!

"Jack and I are super excited to share with you all that we are expecting our second baby!" she wrote on her blog Raddest Mom.

We bet Pearl is excited to have a sibling!

Miley Cyrus is back to work!

On Wednesday the starlet headed to the recording studio in Hollywood to continue working on her new album, and she tweeted, "Sorry I ain't tweeting much. Focused on #BANGERZ." But lucky for us, Pharrell posted the Instagram shot above and wrote, "My little sis' Chanel jacket is so serious..." At least someone is giving us our daily dose of Miss Miley!

After hitting 13 million followers earlier this week, Miley Cyrus took to Twitter to reveal that her new album title is BANGERZ, and we're dying to hear more about her 4th EP. The first single off the album, "We Can't Stop," hit the number two spot on the Billboard Hot 100 Singles chart, and the music video has logged over 123 million views. Give us more!

Angus T. Who? Likely filling the new void on Two And a Half Men, CBS has announced that Amber Tamblyn has been cast on the hit show as Jenny Harper, the illegitimate lesbian daughter of Charlie Sheen's character, the late Charlie Harper. The former Joan of Arcadia actress will have a recurring role in five episodes with an option to become a series regular for the show's 11th season.

To work Tamblyn into the show, the 30-year-old's character will arrive at the home of Walden Schmidt (Ashton Kutcher) and Alan Harper (Jon Cryer) in search of her father, whom she learns has unfortunately died/aka had a meltdown of crazy in 2011 and the show's creators had to kill him off. If viewers like Tamblyn, the plan would be to make her a permanent fixture in the Schmidt/Harper household.

Show creator Chuck Lorre explained at the Television Critics Association's summer press tour in July why they chose to add a woman to replace Angus T. Jones:

"I think it would be great to have a voice on the show from a different perspective. The show has had enough testosterone to last a lifetime ... Part of the fun in this has been creating a character that is equal to the task of stepping on the stage with Jon Cryer and Ashton Kutcher. That's a big job. The idea of the character brings a healthy amount of decadence, which is always fun on Two and a Half Men."

A Seventh Day Adventist, Jones' departure from the sitcom was announced in May, following months of rumors that he was leaving the show after posting a controversial YouTube video in November 2012, in which he called the show filth and warned viewers not to watch. Never a smart move for the star of a show! Jones later apologized for the video -- but the damage had been done.

With all these cast changes -- Two and a Half Men is looking more like Sisterhood of the Traveling Sitcom!

Thanks for clearing things up, Jen!

Jennifer Aniston made an appearance on CBS' The Talk yesterday to promote her new movie We're The Millers, and the actress chatted with the ladies about the pressure the public puts on her to walk down the aisle with fiance Justin Theroux.

"We're just really happy and we're in love and we feel like we're married. Eventually we're going to get married when we find the time. I don't feel like there's a rush," she explained about taking her time with the nuptials.

After co-host Aisha Tyler commented how quickly people expect you to wed after getting engaged, the 44-year-old couldn't agree more!

"I was supposed to have it [the wedding] in March, I think. And I was like, 'What? I'd like to be part of this planning'," she joked.

Looks like we're going to have a little bit longer for the wedding of America's sweetheart!
