Loved ones of pop star Lily Allen have told her to slow down with her weight loss as she continues to shed the pounds.

Lily shrank down from a size 12 to a size 8 as she returned to the spotlight recently after a two year break.

But the 28-year-old singer’s friends and family now fear she’s becoming unhealthily thin and is obsessed with her figure as her fame continues to climb.

Lily previously spoke about how ‘reprogramming’ her brain helped her lose the weight.

“After the hypnotism, I want to go to the gym every day, otherwise I feel really bad. I just want to get more toned and healthy. I’m really good about everything at the moment – I’ve never been happier,” she said earlier this year.
