sunglasses heels Gwen Stefani blazer pregnant zuma

Even rock 'n' roll families love the Super Bowl! Rockin' parents Gwen Stefani and Gavin Rossdale took sons Zuma and Kingston to a Super Bowl party at Siren Studios in Hollywood.

Even nine-months-pregnant and at a Super Bowl party -- Gwen looks flawless! Wearing all black, the 44-year-old outfitted herself in a pinstripe blazer, tunic, leather leggings, and suede wedge ankle boots. Gavin also opted for a dark ensemble, wearing black jeans, a puffer jacket and a beanie. If the pregnant mom-of-two and her hubby are Broncos fans -- they're definitely wore the appropriate outfits to mourn Denver's crushing defeat by the Seahawks.

Their tow-headed sounds opted for a little more color in their ensembles -- both wearing red from head to toe.

At the parking lot bash, Gwen stopped by different tables while her boys enjoyed throwing around the football!

At least someone had some fun yesterday -- because it certainly wasn't anyone on the Broncos!
