Rosie Huntington-Whiteley is back at her day job as a hot bikini model after her whirlwind Hollywood acting debut in “Transformers: Dark of the Moon.” Not that anyone should complain; Rosie sizzles for Victoria’s Secret.

The 24-year-old English model rocketed to stardom after Director Michael Bay picked her, seemingly out of the blue for the role Megan Fox played in the two previous Transformers movies.

Her only previous acting experience was for a Victoria’s Secret commercial that was directed by none other than Bay.

Rosie gave a credible performance as Shia LaBeouf’s love interest in the movie. Since its June 29 release, the picture has been a box office smash, despite mediocre reviews.

As of July 19, it’s grossed $308.78 million domestically and $782.76 million worldwide, according to Box Office Mojo.

She’s been a regular for Victoria’s Secret since 2006, but surprisingly she remained relatively unknown until she got a big break in 2008.

She was tapped that year by chief creative director Christopher Bailey to replace British supermodel Agyness Deyn for Burberry’s fall/winter campaign with actor Sam Riley.

After that her modeling career and profile took off, and this year she hit a new high.

In March, she landed her first solo British Vogue cover. In May, she was voted No. 1 in Maxim magazine’s “Hot 100” list.

She was also voted No.1 in FHM’s World’s Sexiest Woman 2011 poll, and this month covered both the UK’s Elle and GQ editions.

After her impressive movie debut, it might be hard for Victoria’s Secret to keep her in a bikini in front of a camera. So check out these photos and enjoy.
