Lady Gaga may not be too pleased to see Cameron Diaz getting stuck into her boyfriend Taylor Kinney.
But the singer needn't worry, as it's all for a film the pair are starring in called 'The Other Woman'.

The pair were snapped locking lips as they filmed on location in New York on Wednesday.
The cameras started rolling on the comedy flick back in April, which also boasts Nicki Minaj and model Kate Upton among its cast.

Taylor - who has also starred in 'Vampire Diaries' and 'Chicago Fire' - has been busy taking care of Gaga following her hip surgery earlier this year.
The 'Bad Romance' singer was forced to cancel the remaining dates of her tour after being forced to have an operation, but is now finally on the mend.
