Lady Gaga's Monster Ball Tour returns to the U.S. on July 1, after playing stadiums and arenas around the globe for the past five-plus months. So naturally the only thing for the tireless superstar to do was announce even more North American dates ... for 2011.

Yes, Gaga's schedule got even more crowded on Monday (May 10) when she revealed a string of new shows set for early next year. The latest leg of her seemingly unending Monster Ball jaunt will kick off on February 19 in Atlantic City, New Jersey, and will make stops in cities like Toronto, Las Vegas and New Orleans before wrapping on April 18 in Duluth, Georgia.

Gaga's pals Semi Precious Weapons will serve as support on all the shows. Tickets for these latest dates go on sale on Friday (May 14). For more information, head to Live Nation's official site.

Lady Gaga is currently touring Europe and will swing back to the U.K. at the end of May. She has roughly four weeks off before returning to the road on June 28 in Montreal, and then she'll launch yet another run of North American shows, which will keep her out until mid-September. She'll wrap up 2010 in Europe once again, and then return to the road with these just announced dates. At some point, she will presumably find time to sleep.
