Cate Blanchett is reportedly pregnant.

The 'I'm Not There' actress sparked rumours she is expecting her third child with husband Andrew Upton after she was pictured sporting an apparent baby bump while leaving New York's Guggenheim Museum on Saturday (27.10.07).

Cate had been performing in the play 'Right You Are (If You Think You Are)'at the famous art centre.

The 38-year-old star kept the bump hidden under a spectacular sequined dress at the premiere of 'Elizabeth: The Golden Age' at the London Film Festival last Tuesday (23.10.07).

However, rumours were further fuelled by Cate's decision not to drink alcohol at the post-screening celebrations.

A source said: "Tongues started wagging when she wouldn't drink after the premiere for 'Elizabeth: The Golden Age' last week. It was such a big night it was strange she didn't join in the celebrations."

Cate and her playwright husband Andrew already have two sons, five-year-old Dashiell and Roman, three.

Earlier this week, it was revealed Dashiell dressed up as a knight and stood guard to protect his mother on the set of 'Elizabeth: The Golden Age'.

Cate said: "In the scene where Clive Owen is talking about the immensities and I'm sitting on the throne, I'm actually looking through an archway at my son standing in a knight's costume protecting me.

"He stood for like five minutes and each take was different for him. He was a natural, unfortunately."
