Jessica Simpson and John Mayer are no longer a couple.
A source close to the singer-actress tells The ShowBuzz that they broke up last week.
The source says that things may not be over for good since Simpson and Mayer have split up before.
"They're still talking," the source said.
Simpson's rep, Lauren Auslander, told The ShowBuzz that "we don't comment on our clients' personal lives."
The Web site TMZ reported Friday that Mayer was at the New York club Stereo by himself on Thursday night.
Celebrity blogger Perez Hilton first reported news of a split on his blog.

The pair were hand in hand just over a week ago at the Metropolitan Museum of Art's Costume Institute Gala on May 7 in New York City.
Word that Simpson and Mayer were an item began circulating last August but the couple were mum on the topic. Sometime after they began popping up at events.
They got quite cozy in the V.I.P at Christina Aguilera's New Year's Eve bash at the Hudson Hotel in New York City. Simpson also recently spent time with Mayer in Italy.
Her divorce from singer Nick Lachey was finalized last June. Lachey is dating TV personality Vanessa Minnillo.
