Jennifer Lopez Working with Choreographer Boyfriend Casper Smart for Tour

Jennifer Lopez wants to marry her boyfriend Casper Smart.

The 42-year-old singer is thought to be ready for a fourth trip down the aisle after announcing she was parting ways with Marc Anthony last July.

A source told Us Weekly: "She's telling friends she wants to marry Casper. She's certain she wants to be with Casper forever."

At a press conference on Monday (05-30-12) to announce her upcoming world tour with Enrique Iglesias and Wisin Y Yandel, Jennifer announced her partner of six months will play a vital part in putting the show together.

"I'm working with [choreographer] Jamie King, and also Casper Smart. It's going to be an amazing, amazing show."

She added that the event will be "one of the most historic tours ever."

She continued: "There's never been something like this, where Latinos come together like this. It's international - English and Spanish. I just think it's very groundbreaking. I was honored to be asked to be a part of it."

Jennifer has previously been married to restaurant waiter Ojani Noa and former backing dancer Chris Judd.
