• During a break from his jury duty, Jake Gyllenhaal hosted an impromptu autograph session for two lucky ladies at L.A.'s county courthouse. Apparently the actor's attempt to go unrecognized – he wore a baseball hat – didn't work.
• Amanda Bynes, getting close to a guy while dining with friends at Las Vegas's SushiSamba. "They definitely seemed cozy and flirty," a source tells us, adding that the new guy was tall and skinny with dirty blonde hair. "At one point, the group was taking pictures ... and the boy had his arm around Amanda."
• Also in Sin City: Usher, grooving into the two-story LAX Nightclub. The R&B star was joined by a large group of friends – including Jermaine Dupri – and he partied the night away at a VIP table onstage, swilling champagne while DJ Hollywood spun.
• It was date night for Jamie-Lynn Sigler and Jerry Ferrara at West Hollywood's Il Sole. Onlookers say the couple, who sat in a corner table, were totally into each other – giggling, holding hands across the table and eating off each other's plates. Their entrée choices? Sigler opted for the Dover sole while Ferrara went for the meatball special.
