What breakup?

One month after announcing their split on England's The Graham Norton Show, Lady Gaga, 25, has reconciled with musician and bartender Luc Carl, 30.

The "Edge of Glory" singer -- who told the talk-show host, "I don't have a boyfriend" -- now says she stretched the truth. Indeed, the New York-born star admits she has been less than forthcoming when discussing her love life in interviews, telling Us Weekly, "I sometimes skirt questions about it -- and maybe not honestly."

Still, a source confirms to Us that the couple of one year did split briefly. "They had a little fight," says the pal. "I think the breakup lasted a week or two."

Adds the insider, "They are totally back together now."
