Beyoncé announces world tour -- 'The Mrs. Carter Show'

Beyoncé's Super Bowl appearance was unusual because it didn't launch anything new. There was no new single, no new album details, not even a pregnancy announcement.

The big reveal actually happened Monday, as Beyoncé announced her world tour, "The Mrs. Carter Show," a yearlong journey that kicks off in Belgrade, Serbia, on April 15. The American tour starts June 28 in Los Angeles and ends Aug. 3 at -- where else? -- Brooklyn's Barclays Center, which is partially owned by husband Jay-Z, born Shawn Carter. Tickets for the Brooklyn show go on sale at 10 a.m. Feb. 11 through Ticketmaster, though ticket prices have not been announced.

"The Mrs. Carter Show," which also will include high-profile performances at the Glastonbury Festival in June and Rock in Rio in the fall, is Beyoncé's first major tour since 2009 and the first since the birth of her daughter, Blue Ivy. She is at work on the follow-up to her album "4," though no release date has been set.

Ratings for Beyoncé's halftime show Sunday nearly matched Madonna's from last year, with Beyoncé landing a 48.2 rating and a 71 share, according to Nielsen, compared with Madonna's 72 share and 48.1 rating. Unlike Madonna, though, Beyoncé wasn't the most-watched part of the game: The audience built as the San Francisco 49ers closed the gap on the Baltimore Ravens as the game drew to a close.

Sales of Beyoncé's closer "Halo" pushed the song into the iTunes Top 20 Monday, while Beyoncé's album "4" moved back into the Top 15. Those sales are a far cry from previous Super Bowl performances, where new songs immediately topped the charts.
