Jennifer Lopez earned a reported $1 million for performing at a wedding in the Ukraine.

The singer-and-actress - who, last week, announced her seven-year marriage to Marc Anthony was over - flew into the Ukraine yesterday morning (19.07.11), to perform at the nuptials of billionaire Serhiy Taruta's daughter in the evening.

A source told Us Weekly magazine: "He's a wealthy guy who wanted J.Lo and was willing to pay top dollar."

Following her separation with Marc, friends close to Jennifer - who has three-year-old twins, Max and Emme, with the Latino singer - she has thrown herself into work as it is helping her cope.

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

Both Jennifer and Marc - who married in 2004 - admit it was a "difficult decision" to end their relationship.

They said in a statement: "We have decided to end our marriage. This was a very difficult decision. We have come to an amicable conclusion on all matters.

"It is a painful time for all involved and we appreciate the respect of our privacy at this time."
