Russell Brand and Geri Halliwell dating?

Russell Brand's romance with former Spice Girl Geri Halliwell is reportedly getting "very serious."

Russell's divorce from Katy Perry was finalised in July and the British comedian has had a number of romantic affairs since the pair split late last year.

After following head over heels for her at this month's London 2012 Olympics Closing Ceremony, Russell has apparently now moved on to dating Geri.

"Things are getting very serious between them — they're a proper couple now," a source told UK newspaper The Sun.

"They had met several times in the past, but really got to know each other during the Olympics.

"People thought Russell was joking at the time, when he said he had a crush on Geri all over again, but it was true.

"They just clicked — they have so much in common.

"He is spending so much more time in London just to be with her."

Russell ended his brief romance with Isabella Brewster earlier this month in order to make himself available for Geri.
