Lopez estranged from her mother?

Jennifer Lopez is "barely on talking terms" with her mother - because she is too busy to pick up the phone, according to US reports.

The singer/actress, 38, is believed to have grown distant from her once-cherished mother, Guadalupe, who cannot confirm reports her daughter is expecting a baby, because they are not talking.

She tells New York Daily News: "I didn't hear about it. You know more than I do. I don't talk to her very often. I don't see her often.

"She is very busy here taking care of my sister. (Jennifer is) very busy doing what she does."

It is believed Lopez's marriage to Marc Anthony may have frayed relations between mother and daughter.

Lopez admitted in a 2005 interview: "My mum's tough. I don't want to get into that because it's a little personal and she gets angry with me when I say things. But, you know, she loves me a lot, so no-one's good enough."
