UPDATE: Kate has denied engagment rumours during her interview with Graham Norton.
Reports today claim Kate Hudson and Matt Bellamy are secretly engaged. The couple arrived in London on Monday, with Kate giving us a peek at her baby bump for the first time since news broke she's pregnant. That evening they apparently hosted a family party at a hotel in London to celebrate their engagement. Kate's mum Goldie Hawn is in the country, having presented at the British Comedy Awards at the weekend. Congrats Kate and Matt!
