BEIJING, April 4 -- Jennifer Lopez loves "everything" about being a mother.

    She explained to Us Weekly magazine: "What's the best thing about being a mom? Everything! Oh God, I could talk for a year about that!"

    The 39-year-old beauty - who gave birth to the tots in February last year - likes nothing better than watching her "wonderful" babies.

    She said: "They're walking, they're talking, they're babbling a lot - all that kind of stuff. It's wonderful to watch! They're very in tune with each other."

    Jennifer - who gained almost 50lbs during her pregnancy - claims her now-slender figure is down to a good night's rest.

    She added: "Sleep is key to staying in shape. It makes everything better."

    The star recently revealed she wants to expand her brood in the future.

    Jennifer said: "I definitely want to have more. I don't know if it's in the cards for us, but I would like to."
