Jennifer Lopez doesn't give advice to expectant mothers - because it would be "annoying".

The 'American Idol' judge has two-year-old twins, Max and Emme, with her husband Marc Anthony and admits during her own pregnancy she got upset with the amount of women who wanted to tell her how to deal with her ever-expanding bump.

She told Britain's OK! magazine: "Everybody gives you a lot of advice when you are pregnant, which I find a tiny bit annoying, so I'm not going to give any.

"But I did read 'What To Expect When You Are Expecting' by Heidi Murkoff and Sharon Mazel. You can go day by day with that. It's awesome."

Now the twins are approaching their third birthday on February 22, the 41-year-old star has revealed they have settled into a friendly relationship with one another.

She added: "They're starting to play with each other more but there was a time when they were really fighting, a lot.

"He (Max) wouldn't mean it, but he would push her (Emme) and she would get upset and try to bite him. They were like battling it out for position.

"Now they hold hands and walk around - it's very cute. They're lovely together and they give each other hugs and kisses."
