In between her 'Good Morning America' on-stage performances of 'Hold It Against Me' and 'Big Fat Bass' -- shot at the Bill Graham Civic Auditorium in San Francisco -- Britney Spears ecstatically announces to ABC anchor Robin Roberts, and in the company of her dancers, that she plans to co-headline a summer tour with the biggest Latin pop singer in the biz.

As casual as Brit's backstage attire in a flirty white top and jeans, the songstress chats with Roberts, sweetly stating, "We're going on tour with Enrique Iglesias in June!"

The big announcement follows rumors over the past couple of days that she may pair up with another pop star. At first, the tour collaboration doesn't seem like the right fit, but Enrique and Britney are in fact the epitome of turn-of-the millennium pop music, churning up dance hit after dance hit in the 10 years that followed. Plus, Enrique just dropped his debut bilingual album, 'Euphoria,' last summer, featuring the Pitbull-assisted hit and 'Jersey Shore' acclaim 'I Like It' -- which is a perfect addition to Spears' pop confection.

UPDATE: According to Billboard, Enrique pulled out of the North American tour just a mere hours before her 'GMA' performance. Live Nation has yet to comment.
