Jennifer Lopez, Casper Smart: Singer Gushes About Relationship With 25-Year-Old Boyfriend

Jennifer Lopez sure isn't shy when it comes to describing just how she feels about her 25-year-old boyfriend, Casper Smart.

"He's fantastic; he's like my best friend," the singer, 43, revealed in the February 2013 issue of Harper's Bazaar. "I can tell him everything, when I'm feeling down, when I'm feeling good. He gives moral support, endless love and support."

Rumors of Lopez's relationship with Smart -- who is a dancer and the creative director of her "Dance Again" tour -- surfaced after he was spotted leaving her New York City hotel back in November 2011. In September 2012, she told Katie Couric that the 18-year age gap between the couple doesn't faze them.

"It's hard for me to think of my age... I feel very youthful," Lopez told Couric. "And I feel very comfortable in my own skin. And it's funny, until somebody brings up [the age difference], I don't think we really think about it."

The former "Idol" judge split from her husband of seven years, Marc Anthony, in July 2011. Anthony filed for divorce in April 2012. The pair has two kids together, four-year-old twins Max and Emme.
