Model Behati Prinsloo tucks her hair back for the cameras during a photoshoot for Victoria's Secret at Central Park in New York City. (Dig that cute little braid.) This happened on May 20, 2013, which appears to have been a beautiful spring day. Behati Prinsloo was born in 1988, so she turned 25 the year this photo was taken.
"On the loose" is more of an exuberant description than a factual one; she IS at work, after all. "Pink" is a sub-brand of Victoria's Secret, so perhaps the color of the sweater was no accident.
