Jennifer Lopez's boyfriend Casper Smart reportedly wants to marry after he's financially successful.

The 43-year-old superstar and the 25-year-old backup dancer began dating a few months after Jennifer separated from her third husband Marc Anthony in July 2011.

Apparently Casper is eager to pop the question.

'He's telling his friends and family that he is going to propose soon,' a source told In Touch magazine.

'He wants to marry her, and she's told him that she's ready, even though this would be her fourth marriage.'

Casper is currently dancing on Jennifer's international concert tour that began last summer.

Apparently Casper will ardently dedicate time to his professional future when the performances are over.

'He wants to pull his own weight [financially],' the insider explained.

'So when they get back to L.A. after her world tour, he's going to work on getting a new business off the ground.'

Jennifer shares four-year-old twins Max and Emme with Marc.
