Chris Martin reportedly had an affair with assistant while appearing on 'SNL'

Following Gwyneth Paltrow and Chris Martin’s “conscious uncoupling,” NBC is abuzz that the Coldplay singer had an affair with an assistant after appearing on “Saturday Night Live” reports The New York Post.

The couple, who announced their enlightened split last week after 10 years together, are said to have had an open marriage, and both had dalliances, according to sources.

NBC staff have been buzzing about an affair Martin had after appearing as the musical guest on “Saturday Night Live“ in 2011 with Coldplay. Martin also made an appearance on “Weekend Update” with Fred Armisen and Kristin Wiig as Garth & Kat.

One source tells us the girl in question was an assistant on the show, while another NBC source explained, “He had an affair with a woman who was backstage and was part of an entourage. Everyone was talking about it because he was openly flirting with her at one of the show after-parties.”

While a rep for Martin didn’t get back to us, he has strongly denied other rumored affairs. Paltrow’s spokesman said, “I don’t rep Chris so I cannot address those accusations.” There were also reports that Martin romanced Kate Bosworth in 2009, which were denied by his rep.

Paltrow is rumored to have had affairs with Miami billionaire Jeff Soffer who is now married to Elle Macpherson and entertainment lawyer Rick Yorn. All three have emphatically dened the claims.

Paltrow’s spokesman declared, “We have time and time again denied any romantic relationship with Jeff Soffer and Gwyneth. Your source is either wrong or fake. We will no longer be addressing the insane rumors that have been started by gossips.”

The estranged couple has been amicably “uncoupling” by vacationing with family and friends.
