Adele would "do anything" to win back her ex-boyfriend.

The singer was devastated when she split from her former lover and poured her devastation from the break-up into writing her hugely successful album '21'.

However, she admits she still misses him deeply and wants him back in her life.

In an interview with a US magazine, she said: "It's bittersweet because I wouldn't give up this success for anything. But at the same time, I'd do anything to be with him. I miss him. I do.

"It's hard singing all these songs because it makes me remember how brilliant we were when we were good ... and how tragic it was when we were bad."

Adele, 23, also says she finds it hard to sing 'Someone Like You' because it brings back memories of the mystery man.

She said: "Even now, I get emotional performing that. It was such an honest thing to write."

Despite her feelings, Adele admits she has never told a man she loves him.

She said: "It's hard to share feelings. I've felt them. I just can't say them. God, if I find happiness what will I write about!"
