Sienna and Tom - best pals with Robert Pattinson - have been dating for over a year, and Sienna showed off an engagement ring back in February.

The actress showed off her baby bump style back in May when she attended R-Patz's 26th birthday at Claridge's in London in a stretchy grey jumper dress and black blazer.

Congratulations to the new parents, and watch this space for all the details.
