The former Westlife singer, 35 - who split from his wife Vogue Williams last year following three years of marriage - has "grown close" to the 26-year-old actress while training for 'The Jump' in Austria over the past two weeks and has enjoyed "flirting" up a storm with her away from the slopes.

A source told the Irish Sun newspaper: "They do seem to have grown very close very quickly. They get on like a house on fire and it's obvious to everyone that something is going on between them. Their connection is undeniable."

And, although Louisa was given the boot in last night's (31.01.16) show after losing in the skeleton and air jump, it seems the ex-'EastEnders' star is keen to take their romance to the next level by introducing the Irish hunk to her friends when the show wraps up later this month.

Meanwhile, the pint-sized beauty recently admitted Brian won over her heart when he sung to the group around the fire before the live shows kicked off at the weekend.

She said: "Everyone is getting on really well -- they're really supportive of each other. At night we all sit round the fire. Brian sings us songs. We were all like, 'Oh my God.' "

Brian was previously married to Kerry Katona, with whom he has daughters Molly, 14, and Lilly-Sue, 12. He's also been engaged to Australian superstar Delta Goodrem.
