Three days after announcing her breakup from Justin Timberlake, Jessica Biel put on a brave face to enjoy a night out early Sunday in Los Angeles.

Casually dressed in a leather jacket, white tee and jeans, Biel offered a smile for photographers as she exited Hollywood diner Cafe Entourage, where she celebrated her brother Justin's birthday.

It is the 29-year-old star's first night out since her March 10 split from her boyfriend of four years. See more pics from Jessica's outing.

"The two remain friends and continue to hold the highest level of love and respect for each other," their reps told in a joint statement Thursday.

Adds an insider of the breakup: "It was mutual. Jessica is doing well."
