Chelsea Handler reportedly had a breast lift ahead of 40th birthday

LOS ANGELES, March 4 (UPI) -- Comedian Chelsea Handler reportedly underwent a breast lift ahead of her 40th birthday in February because she was "stressed about looking saggy."

Sources revealed Handler's alleged surgery to Us Weekly, adding that the former E! host is "obsessed" with the results.

"She is obsessed, so she keeps posting," said the insider of Handler, who often shares photos of her breasts on social media.

Handler last shared a topless photo of herself from New Orleans' Mardi Gras celebration, which she attended with good friend Sandra Bullock. The star has often shared her disscontempt with Instagram's nudity policies and has stated the site's rules are sexist.
