The cage-fighter and the glamour model looked smitten with each other as they attended the DVD launch of 'The Fighter' at London's York Hall.
The pair colour co-ordinated their outfits, with Chantelle opting for a black vest top and white jacket, while Alex went for a black and white pinstriped suit, and they couldn't keep their hands off each other as they kissed and cuddle in front of photographers. Alex has been single since splitting from estranged wife Katie Price, while reality TV star Chantelle broke-up with TV presenter Rav Wilding in April.
Since getting together last month, Alex and Chantelle have spent lots of time together and recently spent a romantic mini-break at a spa hotel.
A source said: "Alex decided to whisk Chantelle off for a few days at The Grove - a posh golf and spa retreat near Watford. The England football boys often stay here so Alex figured it would be flashy enough for Chantelle.
"They shared a room had facials and Swedish massages. Even without make-up, Alex thought Chantelle scrubbed up OK."
