Will.i.am and Geri Halliwell are rumoured to be an item
The 37-year-old Black Eyed Peas singer - who is currently working on the UK version of `The Voice`, and the former Spice Girl dined and partied at the Rose Club in central London, according to a source, but went to great lengths to avoid being seen together.
An onlooker told Metro newspaper: "It definitely seemed like they were on a date. "They were both really giggly with each other and were laughing all night.
"They arrived separately and left again at different times after they got word out the paps had found out and were waiting outside."
A representative for Geri, 39 - who is a single mother to five-year-old daughter Bluebell - claimed the `Wannabe` hitmaker had been invited to watch Will perform at the Marylebone venue.
Having split from boyfriend Henry Beckwith after two-and-a-half years in March, Geri has remained single, although was also spotted having dinner with a mystery man in Mayfair earlier this month. She has previously dated Robbie Williams and was once engaged to Italian millionaire Fabrizio Politi, before their relationship ended in early 2009.
