After Super Bowl halftime show, Beyoncé announces world tour

SANTA CLARA, Calif. -- Beyoncé is working overtime this weekend: After releasing a new song Saturday and performing at the Super Bowl on Sunday, she's announced a new stadium tour.

The Grammy-winning singer announced her 2016 Formation World Tour in a commercial after she performed at the halftime show with Bruno Mars and Coldplay. The tour will kick off April 27 in Miami and the diva will perform shows in North America and Europe. The tour wraps on July 31 in Brussels.

Pre-sale tickets for American Express cardholders go on sale Tuesday; tickets for general public will be available Feb. 15.

The singer was last on a stadium tour -- the On the Run Tour with husband Jay Z -- in 2014, a year after she headlined the Super Bowl halftime show in New Orleans. Sunday's halftime performance included Beyoncé's new song, "Formation," released Saturday causing Internet frenzy.

"Formation" is a gritty street anthem that, perhaps not coincidentally for Black History Month, has lyrics that express black pride with an exclamation point. One lyric: "I like my Negro nose with Jackson Five nostrils."

And a cheeky line about her man's sexual prowess earning him a trip to Red Lobster had the seafood chain a top trending topic on Twitter Saturday afternoon.

The video features a brief cameo from her daughter, Blue Ivy, who dances with a group of young girls.
