But lately it's been said that Balthazar wants to return to his family, and Sienna's confirmed she's single.

Speaking at an event in Hollywood she told reporters: "I'm single at the moment, and I’m completely happy with that.

"It's nice not to have a relationship that the press constantly want to scrutinise and discuss. I'm cool with being on my own."

Si did seem to be back in fine fliratious form on her night out with Ollie, however.
