J.Lo, who confirmed last week that her seven year marriage to Marc has come to an end, soldiered on to perform at a private wedding in the Ukraine, telling guests: "I'm happy."
The Im Into You star took to the stage to sing some of her most famous hits for the son of a Ukrainian oil tycoon's nuptials, reportedly receiving a cool $1million for the gig.
According to US Weekly, Lopez stayed in a luxury $4,000-a-night hotel suite during her stint in the Ukraine, with staff telling the publication that despite her recent heartbreak, Jen was "very pleasant" and "smiled a lot."
It is thought that the On The Floor hitmaker even took the time to pose for pictures with fans, before heading off to the wedding venue to perform for 500 guests.
Once on stage, Jennifer apparently exclaimed: "Are you happy? I am happy, because I am here with you today!"
Reports yesterday suggested that Anthony "hated" J.Lo's sex symbol status, with sources adding that his "controlling" behaviour could have contributed to the break down of their marriage.
An insider told the magazine that although Lopez was allegedly "devastated" following the split, she is already "looking forward to the future."
They explained: "She is jumping back into work and being a mom (to twins Max and Emme, aged 3) with all her energy she is really excited."
The source added: "She feels like she has grown leaps and bounds and is a new person now, better than ever!"
