Super Bowl Sunday is always a blast: chillin' with your fave guy friends, munchin' on the best fried foods, but Jessica Biel decided to make her beau Justin Timberlake's day even better. She threw him a Super Bowl-themed surprise party at the Hollywood Roosevelt Hotel's exclusive penthouse on Sunday afternoon to celebrate JT's 28th b-day, according to People. Close to 100 friends and family were in attendance, including both Justin and Jessica's 'rents. Guests munched on gourmet buffalo wings, pizza, mini sliders, and red velvet cupcakes -- YUM! "Justin was totally blown away when he walked in. He had no idea," a source says. Aw! Sounds like a party we'd want to crash!
