Russell and Geri reportedly bonded after Russell sidled up to the singer after her Spice Girls reunion performance at the 2012 London Olympics closing ceremonies.
The Daily Mail claims Russell was so attracted to her he broke it off with his gal pal of a few months, Isabella Brewster.
The funnyman was seen romancing Geri and her six-year-old daughter, Blubell, at Hampton Court Palace this past weekend in London and have been spotted out and about in recent weeks.
"Things are getting very serious between them — they’re a proper couple now," a source close to the pair told The Sun. "They had met several times in the past, but really got to know each other during the Olympics."
Geri shouldn't hold her breath, however, as Russell seems to change girlfriends like he does his underwear.
Speaking of his most famous ex, Katy Perry, the 'California Gurls' singer has just exited a fling with another playboy, John Mayer, and is setting her sights on recently single Robert Pattinson.
The two went on a dinner date, reports The Sun, and the Twilight actor had a hard time keeping his eyes of her ample assets.
"She wore a tight, sparkly top and Rob was looking at her breasts all night. He tried to avoid it when talking to her but as soon as she looked away to talk to someone else, Rob would sneak a peek," reported the spy.
