Leelee Sobieski is engaged to menswear designer Adam Kimmel, a friend of the couple tells Usmagazine.com.

Sobieski, 26, donned her marquise diamond engagement ring to the L.A. premiere of her latest flick, the Johnny Depp drama "Public Enemies," in Los Angeles June 23. On the red carpet, Sobieski told Us she was "leaving to meet him in Paris" the next day.

The actress rose to fame playing a modern-day Lolita, opposite Tom Cruise, in the 1999 Stanley Kubrick film, "Eyes Wide Shut."

In addition to modeling for her fiance's Fall/Winter 2009 Look Book, she recently filmed the indie drama "The Mad Cow" with Arrested Development star Jeffrey Tambor.
