Jennifer Lopez says it would be "wonderful" to have more children.

The star has four-year-old twins Max and Emme, from her marriage to Marc Anthony. It has recently been reported that Jennifer's boyfriend Casper Smart feels ready to become a father and Jennifer has now revealed that she would consider expanding her brood.

"Yes, that would be wonderful!" Jennifer told the German edition of Grazia when asked if she wants more kids. "For the moment I'm busy enough with the twins."

Jennifer enjoyed the experience of being pregnant, but admits it took a toll on her body.

The 42-year-old has recalled how her figure swelled and she suffered from memory loss, leading to difficulties with her wardrobe and during live performances.

"[My] nose grew and my feet swelled one size! Horrible! I asked myself what I should do with all the wonderful high heels I had!" she laughed. "While on tour I constantly forgot the song lyrics. When you're pregnant your brain shrinks to baby size!!!"

Jennifer's latest big screen outing was for What to Expect When You're Expecting.

She played an expectant parent in the romantic comedy, while Rodrigo Santoro was her on screen husband. The star has laughed that director Kirk Jones constantly had to ask them to tone down their love scenes.

"Our director thought that we were overdoing it with the kissing and smooching," she joked. "He yelled: 'People, let's be more discreet!' But we didn't want to be and said: 'Well, we're Latinos, we're into body contact.'"
