London, Jan 22 (IANS) Rumours are rife that romance is brewing between Hollywood stars Kate Hudson and Gerard Butler after they partied together after the Golden Globe Awards function.

Sources claim Butler, who has been linked to Jennifer Aniston and Lindsay Lohan, set his sights on single Hudson and wouldn't leave the bash until he had secured her number, reports imdb.com.

'Gerard told Kate she was the most beautiful girl in the room and that he adores her work. He was really locked in on her,' said an onlooker.

Hudson has been single since her split from baseball star Alex Rodriguez late last year.
