Jennifer Lopez squirmed with embarrassment when "confronted" by two ex-boyfriends at a wedding, it was claimed today. The singer was among the celebrity guests at movie mogul Harvey Weinstein's wedding to British fashion designer Georgina Chapman in Connecticut last weekend. The Jenny From The Block star was enjoying several video tributes from pals who couldn't make it to the nuptials. But she was silenced when the messages from former flames Sean "Diddy" Combs and Ben Affleck flashed up on a giant screen. One guest revealed: "Jennifer was laughing at all the funny tributes. But when Diddy and Ben gave their speeches, she went silent. She looked sort of uncomfortable and people were staring at her." Mum-to-be Lopez, 38, was at the ceremony with husband Marc Anthony, according to US reports, but a spokeswoman for Lopez was unavailable for comment. Pictures: Kelly Bishop / London Entertainment
