Rollercoaster romance! Kelly Brook and David McIntosh can't stop giggling as they enjoy romantic date at Winter Wonderland

Kelly Brook and her former fiancé David McIntosh looked well and truly back on track as they enjoyed a date at London's Winter Wonderland. 

The on-off couple were first pictured spending time in one another's company on December 14, as they ordered in milkshakes on a weekend trip to Manchester, shortly after David was pictured out with Aisleyne Horgan-Wallace.

And now things appear to be going from strength to strength for the couple who giggled and looked at one another adoringly while enjoying the park's Haunted House ride.

Back on! Kelly Brook was seen out with on-off boyfriend David McIntosh at Winter Wonderland 

It will come as a fresh blow to Aisleyne, who was seen crying in the street last week, which has been linked to her own recent London date with David.

David and Kelly haven't seemed able to tear themselves apart despite Aisleyne's involvement and both admitting to breaking up a number of times. 

Former gladiator David has been pictured with a couple of other women in the short period he split up from Kelly, including Jess Impiazzi and Metisha Schaefer.

It's not the first time Kelly has visited the festive attraction in Hyde Park this year. In November, she visited with rumoured love interest, James Crabtree.

Kelly called herself a single girl in early November but just couldn't seem to keep away from the man who she has enjoyed a whirlwind romance with throughout this year. 

Speaking at the Stand Up for Pitts charity event in Hollywood last month, Kelly revealed she was more interested in animal rights causes like the plight of dogs than her love life.

'Maybe it’s not my time to find love at the moment. I think it's good to focus on myself and other things, like this cause here tonight', she said in a video obtained by MailOnline. 

'There are more important things in the world.' 

David and Kelly intended to tie the knot in Mykonos, Greece before David's ex-girlfriend Sarah Harper came forward in September to claim she had been having an affair with the muscleman.

Kelly was reportedly left feeling 'hurt and humiliated' amid the cheating claims, which David denied - and dumped him immediately, deleting all evidence of their relationship on social media.

She then took him back and was pictured leaving Pace restaurant in West Hollywood with him only weeks after the initial split.

In late November, David told The Sun newspaper: 'Kelly and I are madly in love. No matter what goes on we can't stand being apart. We are back together now.'

But it wasn't to last for long as Kelly reportedly broke up with her former fiancé again after he was pictured leaving the Lingerie Awards with glamour model Aisleyne in early December.

A spokesperson for Kelly Brook declined to comment to MailOnline.

It certainly seemed like David and Aisleyne were linked following the Lingerie Awards when she shared a series of posts with the Gladiator.

But as soon as Kelly came back into the frame, Aisleyne was boasting that she'd made a 'lucky escape' and that David pictured with her in the captioned snap needed 'to learn some manners #disgusted'

A representative for Aisleyne's best friend Nicola McLean later told MailOnline: 'Nicola really likes Kelly and thinks David is a d**k for how he has treated Kelly and for how he lied to Aisleyne and led her on.  

'Nicola thinks Kelly is way too good for David and she could have any guy she wanted. David should be grateful he even has Kelly's phone number, let alone gets to date her.'
