Happy birthday, Rosie Huntington-Whiteley! The English supermodel turns 28 today. The former Victoria's Secret Angel made her film debut in Transformers: Dark of the Moon in 2011, and her flawless beauty has landed her several ad campaigns with major designers. She recently made her debut as the new face of Paige, rocking the brand's latest denim in its spring 2015 campaign, and previously showcased her dreamy hair—which she cut into a trendy lob earlier this year—in Moroccanoil's campaign last year. Her trick to supermodel hair? Find a mane man and never let him go. "The most important thing for me is to make sure I get regular cuts," she previously told InStyle. "I'm very loyal to the people I work with." Want more Rosie? The birthday girl is in the upcoming action-packed film Mad Max: Fury Road.
