Is J-Lo pregnant?

Superstar Jennifer Lopez has increased speculation she's pregnant with her first child - after she revealed a fuller waist than usual while swimming on a tropical island.

The Jenny From The Block singer, who wed Salsa singer Marc Anthony in a surprise ceremony in June, is relaxing on the Caribbean island of St Barts.

Onlookers were surprised when J-Lo's usually perfect waistline appeared to have more weight to it than usual.

One says: "She's really glowing and certainly has a little bit of something around her waist. She may well be pregnant."
