Jennifer Lopez's recent split from Marc Anthony hasn't slowed down her work schedule.

Days after announcing their breakup, the American Idol judge flew to the Ukraine to perform at a wedding for billionaire Serhiy Taruta's daughter. Arriving at 5 a.m. Tuesday, the 41-year-old superstar will reportedly earn $1 million for the gig.

Perhaps some time away from L.A. will be good for Lopez, who was married to 42-year-old Anthony for seven years. "She is devastated," a source told Us Weekly Monday. "Absolutely beside herself. This is someone she dedicated a long time to, and that she truly loved."

"She tried everything she could to make it work," the source added. "They went to marriage counseling. She was patient and loving and did everything he wanted her to. She exhausted all the possibilities."

Lopez has found solace through work in the wake of her recent breakup. On Saturday, the "I'm Into You" singer arrived at MILK studios in L.A. to shoot a fall ad campaign for her Kohl's clothing line.

"She is jumping back into work and being a mom with all her energy and she is really excited," a second insider told Us. "She feels like she has grown leaps and bounds and is a new person now, better than ever!"
