Jennifer Lopez Flaunts Famous Backside, Talks Failed Relationships!

The singer covers the latest issue of Elle UK magazine (via Daily Mail), where she shows off her amazing booty and opens up about finding "the one."

Lopez -- who split from longtime beau Casper Smart earlier this year -- says she's still optimistic about love ... even though the breakup was tough.

"Everybody has seen that I make mistakes," she says. "I rush in, I get swept up and I ignore the signs. But so many of us are guilty of these things."

"Each time it goes wrong, it's hard. I get really hurt but I have to let myself go: 'What did I do? What can I learn?' And as hard and as hurtful as things get, I want to believe I will be able to go one step higher. I've got to hope that if I keep going I will eventually get it right."

Jen and the 27-year-old called it quits after rumors surfaced that the dancer was having sexual relations with a transgender woman while dating Lopez.

The "Booty" singer also split from ex-hubby Marc Anthony in July 2011, and the exes have two children together.

"I'm from a traditional background. It takes two people to make a kid for a reason. It's tough because I know they feel the void of that male presence," she says of her life as a single parent.

"When Marc and I first broke up, I did think: 'I wish I could have held this together.' But when you realize it's not the right thing for anybody, you think: 'OK, well how do we make this work, how do we make this better, how do we make this great for the children anyway?,'" she confesses.

And while the "On the Floor" singer has had a few rocky relationships, she still believes Mr. Right is out there.

"I still believe in love. The nirvana man, he's out there somewhere. But you just have to work at it. You have to work at everything," she reveals.
