Sarah Harding Back With Tom Crane?

Girls Aloud star Sarah Harding has fueled speculation she's back together with her former DJ lover Tom Crane -- after the ex-couple were spotted kissing each other in North London on Monday.

The pair had previously denied they had rekindled their romance, and Sarah even said she had sworn off men for good.

But they both seemed very much on as they were spotted visiting a vet's surgery earlier today.

They then headed back to Sarah’s home together and shared a lingering kiss on the doorstep before the 28-year-old drove off.

An onlooker said, "They looked very much in love -- both seemed to be enjoying the other's company."

Tom and Sarah split last month, with work pressures being blamed on the demise of their relationship. Crane complained that Sarah's pop star schedule meant the two spent hardly any time together.

Sarah recently denied that the pair had rekindled their romance, insisting that she was single, even joking that she was considering becoming a lesbian.

"I don't really want to talk about men at the moment," she said. "I'm really fed up with all of them. I think I might become a lesbian."

The 26-year-old also revealed that she was moving out of her £1million ($2m) Camden home because it has 'too many bad memories'.

"It's all just getting too much for me to handle over here. I have photographers outside my house every day," she said.

"So what I've decided is that I'm going to sell up my home and just escape abroad.

"I'm thinking of seeing the world, you know traveling for a bit just to reflect and clear my head. But I'm not going to do that just yet," she added.
