Nicki Minaj is reportedly set to tour with Britney Spears.

The 'Girls Fall Like Dominoes' hitmaker could be set to become the opening act for Britney's hotly-anticipated summer concert tour after Enrique Iglesias pulled out of the guest slot earlier this week.

According to gossip website TMZ, lawyers for both Nicki and Britney are currently involved in "serious talks" and should have reached an official agreement "in the next day or so".

Nicki has made no secret of her desire to work alongside the 'Hold It Against Me' hitmaker in the past, saying the only other artist she would consider collaborating with while she establishes herself within the music industry would be Britney Spears.

She recently said: "I'm done with collabs. No more collabs for the next two years. Although - Britney's a snatch like me and she's cute. Yes. We might do something."

Meanwhile, Enrique Iglesias has sent his apologies to fans for causing "confusion" over his place in the tour.

He tweeted: "Hey guys, sorry for the confusion regarding a possible tour in the summer with Britney Spears.

"We are on the Euphoria tour and will continue to do so including some soon-to-be-announced dates in US. So hope to see all of you soon.(sic)"
