Lily Allen has been through "absolute hell" over the last year

Speaking to Good Housekeeping UK magazine, Andi said: "You know, Lily nearly broke last year. She's been through absolute hell, and it's been extraordinary to see her rebuild herself.

"I'm incredibly proud of her. Miquita nearly broke when she had to dec lare herself bankrupt but, like Lily, she rebuilt herself."

Miquita added: "It's not been easy for Lily. But we're still silly with each other, and I doubt the playfulness we had as children will ever leave us now."

Following the breakdown of her four-year marriage, the Smile hitmaker got help at a mental health facility, as well as working on a new album, being hospitalised and treading the boards.

She previously said on her Miss Me? podcast with co-host Miquita: "I've done quite a lot this year.

"I've finished an album, I got a boob job, I had a nervous breakdown, I went into hospital for a bit, I came out, I did some podcasting for a while, then I played one of the hardest tracks in theatre and killed myself [in the role of Hedda Gabler] every night for seven weeks."

Lily hints on her latest album West End Girl that ex David was unfaithful to her and admitted her experiences in her second marriage gave her a better understanding of the "pain" first husband Sam Cooper felt in their relationship.

She told The Observer newspaper: "[I've learned there are no] baddies and goodies in a marriage but, having done things that were not very nice in my first marriage, I have a better idea now of the pain I may have inflicted.

"I've learned how horrible it is to be on the receiving end of that."

Lily has found getting divorced "devastating" and has left her struggling to trust other people.

She said: "It's just sort of devastating, really. It keeps you up at night and costs a huge amount of money and just goes on and on and on. And I hate feeling like I can't trust anyone. But there's something about dealing with an ex-partner and lawyers that creates an environment of feeling like you can't trust anybody or anything."
