Army strong! Taylor Swift attended Alessandra Ambrosio's 35th birthday bash wearing the teeniest short shorts with a camouflage jacket on Monday, April 11, in Malibu.

The "New Romantics" singer, 26, flaunted her incredibly long, toned legs in the denim cutoffs, teamed with a black tank and a Saint Laurent Hunter Jacket (which retails for $1,350). She added a quilted handbag and moccasin-style sneakers, both also by Saint Laurent, and her heart-shaped anniversary locket from beau Calvin Harris.

But Swift wasn't the only well-dressed reveler. Lily Aldridge and Rosie Huntington-Whiteley were also in attendance at the fete, held at Nobu Malibu, working their chic off-duty model style. While Aldridge, 30, wore a cream sweater with distressed jeans, Huntington-Whiteley, 28, opted for a fringed leopard jacket and black skinnies.

Since wrapping her 1989 tour in December, Swift has been enjoying her off-time, vacationing with Harris, spending the Easter holiday with her family and visiting Disneyland with Aldridge and her 3-year-old daughter, Dixie.
