The SexyBack singer celebrated turning 28 on Saturday with a surprise party that girlfriend Jessica Biel threw for him on Super Bowl Sunday.

The bash was held in the exclusive penthouse suite of the Hollywood Roosevelt Hotel.

So, what did the festivities include?

The party kicked off in the afternoon just before the championship game with a menu that included buffalo wings, pizza, mini sliders and homemade cupcakes.

“Justin was completely blown away when he walked in," a source said. "He thought they were just checking into the hotel and heading to another Super Bowl party. He stopped dead in his tracks when he opened the door and then gave Jessica a kiss."

The 100 guests, including “Bleeding Love” songstress Leona Lewis, watched the Pittsburgh Steelers triumph over the Arizona Cardinals on two big-screen plasmas. Everyone put in $10 for a Super Bowl pool.

“Jessica was in a simple black cotton dress and flats, and worked the room like the perfect hostess," the source said."She took breaks to sit with Justin, hold hands and relax."

Wonder if JT is planning on doing something similar for Biel’s upcoming B-day. She turns 27 on March 3.
