Jennifer Lopez has declared that she is 'happy' just days after announcing her split from Marc Anthony.

The 41-year-old singer was performing at a wedding in Ukraine on Tuesday when she spoke out about how she was feeling.

Jennifer was reportedly paid $1 million to sing at the lavish nuptials of the son of Azam Aslamov, who is an Uzbek oil tycoon.

She performed to 500 guests at a recreational complex on the Black Sea coast and wowed the crowd with an energetic show.

'Are you happy?' she screamed while on stage. ' am happy, because I am here with you today!'

There have been reports the American Idol judge was 'devastated' and 'beside herself' over the end of her seven year marriage.

But another source has told Us Weekly that Jennifer 'is looking forward to the future'.

'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!' the insider explained.

Jennifer and Marc are parents to three-year-old twins Max and Emme.
