Lily Allen has played her last gig before taking a break from music to become a mother.

The pregnant singer thrilled fans as she headlined the final night of the Big Chill festival in Herefordshire on Sunday (August 8).

Referring to her pregnancy, she told the crowd: "Excuse my casual attire but I'm pregnant and this is called the Big Chill.”

She also joked that she had packed high heels but that her boyfriend Sam Cooper had unpacked them.

Allen and Cooper, who have been dating since July 2009, announced their baby news last week.

It is unclear when Allen will return to music.

In February, she announced she was taking a break “because I just don’t really want to go on the road for another three years”.

As well as becoming a mother, Allen is also thought to be setting up her own record label and fashion store.
