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.

"She's telling friends she wants to marry Casper. She's certain she wants to be with Casper forever," a source said.

At a press conference on Monday 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."

"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," she added.
