Jennifer Lopez is "trying to make one more baby" with husband Marc Anthony. The 39-year-old actress - who welcomed her first children, twins Max and Emme, into the world in February - is said to be desperately trying to conceive again.

A source close to the couple told In Touch Weekly magazine: "They were advised to wait six months after she gave birth. They listened to their doctor's advice, but now they're trying to make one more baby."

Jennifer Lopez says she has been in a "few challenging" relationships. The 39-year-old star - who has previously dated P. Diddy and Ben Affleck - admits she lost touch with herself during past romantic dalliances.

Speaking at The Women's Conference in Long Beach, California, Wednesday, Jennifer said: "I have been in a few challenging relationships. I have been in relationships that can make you doubt who you are and what you are capable of, and doubt what you deserve. It took me a bit little longer to get it right."

Jennifer Lopez and Marc Anthony renewed their wedding vows "on the spur of the moment" Sunday morning.

The singer-and-actress and her singer spouse decided to reaffirm their love for each other following a night out with friends New York Mets outfielder Carlos Beltran and his wife Jessica, who also renewed their vows at Las Vegas' Caesars Palace's Forum Tower Penthouse.

Jennifer Lopez says her baby son screams like her husband. The star, who gave birth to her first children with Marc Anthony - twins Max and Emme in January, revealed they already have very different personalities.

She said: "Max is like Marc. He's got Marc's lungs, and he screams and he's strong, very boyish. Emme's very delicate and quiet, but you can't mess with her."

Jennifer Lopez suffered a nervous breakdown after working too hard. The singer-and-actress, who has two children with husband Marc Anthony, was working on movie "Enough" in 2002 when she "froze" and realized she had to slow down.

She told website The Daily Beast: "There was a time when I was very overworked and I was doing music and movies and so many things. I was suffering from a lack of sleep. And I did have a kind of nervous breakdown. I froze up in my trailer. I was like, 'I don't want to move. I don't want to talk. I don't want to do anything.' It was on that movie 'Enough.'"
