Hazel who? Calum moves on with model Madeline

Last week, he was snapped enjoying the company of his good pal Hazel O'Sullivan (inset) after the pair of them attended a nightclub opening in Meath and then went to Croker for the big semi-final clash against Dublin and Mayo.

And now he has set tongues wagging after hitting the town with a new beauty, namely Madeline Mulqueen (21) -- with reports suggesting they are more than 'just good friends'.

The Diary can reveal how the pair were inseparable after turning up to the Style of Dublin celebrity fashion night which took place at No 37 Dawson Street on Sunday night.

They posed for pics together on the red carpet and spent a lot of the night chatting together in the smoking area outside the bar as they soaked up the atmosphere at the booze-filled bash.

Looking stunning in a peach mini-dress, model Madeline has never looked better after dyeing her hair dark brown in a glossy make-over which clearly caught the eye of the Celebrity Bainisteoir star.

They joined celebs including Brian Kennedy, Brendan Courtney, Virginia Macari, Paul McGrath and Shay Healy, with some of the socialites taking to the catwalk themselves to model some of the fashionable creations.

Calum and Madeline enjoyed themselves so much at the fashion bash, held in aid of Acquired Brain Injury Ireland, they decided to head on to Lillie's Bordello with a group of pals to continue the fun.

Then on Monday, they met up for a lunch date at Wagamama and she even joined him at a tattoo parlour where he got a new tattoo on his chest.

Madeline and Calum were making no secret of their budding friendship either, given that the Limerick beauty tweeted a cosy pic of herself and the reality star, saying "Loving life@CalumBest xxx."

She posted up the pics in the early hours of Monday morning and was clearly enjoying his company as they partied the night away together.

And the ex-boyfriend of Georgia Salpa returned the favour by posting up a pic of himself with Madeline and a group of girls, saying: "It's not a bad life in Lillie's."

"They had a great time together. It was a bit of a flirtation and who knows, it could lead to something more," said an insider.

"She's a stunning looking girl and she would definitely be Calum's type so it may well be a case of, watch this space."

Obviously a popular lady, just last month saw the star of the Rubberbandits hit Horse Outside pictured with Made In Chelsea star Spencer Mathews during his trip to the Wright Venue.

He was apparently quite taken with the petite model, who was one of the participants in Celebrity Come Dine With Me and is currently single.

She split from her long-term boyfriend Brian O'Brien last April and hasn't been publicly linked with anyone else since then.
