It could have been nothing more than a round of canasta! But judging from the shell shocked expression on Sienna's dog's face, we're inclined to believe it was something more than that. Like erm, a game of Go Fish. Or on the other hand, lots of sexual intercourse.

And according to reports the pair, who became engaged on Christmas day in 2004 (could history be repeating itself and Jude be about to propose again?) have been meeting in secret for a while (although they didn't do a good job of it on this occasion and even had a police escort) and have even shared coffee dates and nights in at Jude's apartment.

Since they've been apart, Sienna became involved with married dad and billionaire Balthazar Getty before making an even bigger mistake and dating trance DJ Slinky Wizard, while Jude's become a daddy with a model after a one night stand. In other words, could these two be any more suited?

On another note, while Sienna's not shacked up with her ex, she's trying to steal theShittest Shoe Showdown crown from Chanelle/Chantelle and thus been spending her time shopping here...
