According to sources the two, who were allegedly dating each other some time back, were attending Mubina Rattonsey's birthday on Friday night at her Bandra pad.
The get-together apparently went on till the wee hours of the morning and a close friend of PC confirmed her presence at Mubina's house.
A friend of Mubina (the daughter-in-law of producer Farouq Rattonsey) says, `It was her birthday and since Priyanka is very close to her, she went to wish her at her home.`
However, apparently once Shahid and PC realised that shutterbugs had got a whiff of their presence in the building, a cat and mouse game ensued.
An onlooker says, `Their cars maneuvered their way in and out of the building. Shahid left first around 3.30 am. Priyanka's car that had left the building a while ago returned shortly to pick up the actress, as she went out through another exit.`
Both Sasha and PC remained unavailable for comment.
