Born in Beverly Hills, CA, Garrett was one of two girls raised in the Santa Monica mountains area of Topanga Canyon. As a youth, her fresh-faced looks had modeling agents circling. One agent in particular managed to recruit her for work after spotting her at a Santa Monica mall, so by the time she had entered high school in the 1990s, she was a client of the famed Elite Modeling Agency. Garrett was then pulled into the world of GUESS fashions by founder Paul Marciano and had become a staple of a variety of clothing advertisements by the end of the decade. After several years of successful modeling, Garrett made a relatively hassle-free transition into Hollywood with a few small screen appearances. Early in 2004, she officially kicked off an acting career, filming an episode of Fox's short-lived Hawaii drama "North Shore" (2004-05). That same year, she famously appeared on HBO's popular Hollywood insider comedy, "Entourage" (2004-2011), playing the much talked-about Fiona, a sexy object of desire for the series' fictional rising star Vince Chase (Adrien Grenier). Over 12 days in September 2004, the eager Garrett headed back to Hawaii to shoot a pilot for The WB entitled "Rocky Point," which was not picked up to become a series. In early 2005, Garrett appeared in the pilot for another Fox series, the short-lived comedy "Head Cases" (2005), which began airing that September. Over her summer, she was filming an independent horror thriller "Unearthed" (2007), as well as John Stockwell's "Turistas" (2006) for the newly-formed Fox Atomic division. For "Turistas," Stockwell - who was behind "Rocky Point" - once again turned to Garrett to round out his cast, snagging the young actress to appear in the film about young tourists on a Brazilian vacation gone fatally wrong. In the summer of 2006, hot off the heels of her big screen debut, Garrett was giving her acting a serious push, filming the reality television mockumentary "Live!" (2007), before signing on to appear in the big-budget sequel "Fantastic Four: Rise of the Silver Surfer" (2007), in which she played the girlfriend of Johnny "The Human Torch" Storm (Chris Evans). Garrett returned to theaters as part of the cast of the Patrick Dempsey/Michelle Monaghan romantic comedy, "Made of Honor" (2008) prior to reteaming with her "Turistas" cohort Olivia Wilde for the decades-in-the-making sci-fi sequel, "Tron: Legacy" (2010). The year 2010 was a busy one for the actress, who also made guest appearances on such popular television series as "House M.D." (Fox, 2004-2012) and the FBI procedural, "Criminal Minds" (CBS, 2005-). Her guest spot on the latter was no mere coincidence, as it was part of a planned launch for a spin-off show of its own. The next year, alongside a cast that included such diverse talents as Forest Whitaker and Janeane Garofalo, Garrett was seen as a regular cast member of "Criminal Minds: Suspect Behavior" (CBS, 2011). Unfortunately, the program failed to hold the same audience attracted by its progenitor and was cancelled within its first season. Looking to move on to bigger things, Garrett turned up in the crime feature, "Freelancers" (2012) alongside former "Suspect Behavior" co-star Whitaker, rapper-actor 50 Cent and the indefatigable Robert De Niro. After starring in the indie romantic comedy "Lust For Love" (2014), Garrett joined the cast of the drama "Girlfriends' Guide to Divorce" (Bravo 2014-) as Phoebe Wells, a recently-divorced former model attempting to make sense of her new life.
