Jennifer Lopez admits it was an "uphill struggle" to lose her baby weight. The singer-and-actress - who gave birth to twins Max and Emme in February 2008 - gained 50lbs when she was pregnant and was shocked when it didn't fall off straight away.

She said: "I thought the weight was going to drop off easily because I'd been in shape my whole life. But it wasn't easy. It was an uphill struggle. I had gained about 50lbs while pregnant. The first 30lb dropped off like that and I was so pleased. Then I had to lose the last 15 or 20lbs that just didn't want to go.

Jennifer Lopez uses a webcam to keep in touch with her children. The singer-and-actress - who gave birth to twins Max and Emme in February 2008 - can't bear to be parted from her family, so uses the internet to check on how they are doing.

She said: "I hate being away from my kids. But we have devised this thing where I can see them on the computer. I call up on the web camera so I can see the babies while I am away and I just look at them."

Madonna had her phone confiscated at Jennifer Lopez's 40th birthday party. The singer and other celebrity guests, including Rihanna, Beyonce Knowles, Alicia Keys and Mary J Blige, were forced to hand over their mobile phones and any cameras before they were allowed into New York's Hotel Griffou to celebrate with Jennifer last Friday.

The strict rules angered some partygoers, but Madonna and Rihanna reportedly used the increased privacy to dance "exuberantly" to Rob Base and DJ EZ's hit "It Takes Two."
