(Cover) - EN Showbiz - Jennifer Lopez is reportedly eager to focus on her career before having more children.

The 41-year-old singer-and-actress is happily married to musician Marc Anthony, with the pair set to renew their wedding vows on June 5 in honour of their seven-year anniversary.

The couple already have three-year-old twins Max and Emme, and reports suggest that although Jennifer wants to expand her family, she is focusing on her successful pop comeback right now.

"J-Lo would love more kids but she's been reluctant to try this year because she really wants to maximise her comeback," a source is quoted as saying in Closer magazine.

Jennifer's career is going from strength to strength at the moment. The beauty enjoyed success as a judge on this year's series of reality show American Idol, and her seventh studio album Love? has been storming the charts. She also topped People's annual poll of beautiful people earlier this year.

Apparently Jennifer thinks next year could be a better time for her and Marc to add to their brood.

"She wants to wait until next year as she's in the best shape of her life and has never been in such huge demand," the source added. (C) Cover Media
