Jessica Biel is a single girl again – and she's stepping out on the town.

The actress, who is no longer dating her boyfriend of more than three years, Justin Timberlake, appeared happy as she left Café Entourage in Los Angeles Saturday night.

Dressed in jeans, a leather jacket and donning a long feathery earring, Biel, 29, smiled for photographers outside Hollywood's sleek new all-night diner, where she celebrated a birthday of her younger brother, Justin.

And why not show off her gorgeous smile? A source told PEOPLE of Biel's split with Timberlake, 30, "There are no hard feelings."

Adds another source, "There really wasn't a final straw. They're just two people who realized they wanted different things in life and were headed in different directions."
