Britney Spears reportedly stunned onlookers when she accidentally flashed her breasts while playing on a swing.
The pop babe had taken baby son Sean Preston for a walk near her Malibu mansion when she allegedly gave the impromptu show.
The sexy star was rocking backwards and forwards on the swing, which made her sheer top ride up, exposing part of her chest.
A source is quoted as saying: "Britney was out for a walk with her baby Preston and some friends when she had a go on the swings.
"She must have been having so much fun she didn't realise the accidental strip show she put up - other mums looked quite shocked."
Meanwhile it's been claimed Britney is considering having another baby with husband Kevin Federline.
The singer reportedly hopes having a second child will help the pair heal their troubled relationship following a string of bust-ups.
An insider is quoted in Scotland's Daily Record newspaper as saying: "She wants to have another baby as soon as possible to bring them closer together."
