Lily Allen plans to "fill her house with kids" says a source.

The British star gave birth to Ethel Mary in November of last year. Insider says the 26-year-old mother is now keen to extend her brood with husband Sam Cooper.

"Lily's feeling great. The hard no-sleep' part of being a new mum is almost over Ethel is now starting to sleep really well. Lily loves being a mum and has said she plans to fill her house with kids," a source told British magazine Closer.

"She's spoken to her manager about work opportunities, but she wants Ethel with her for anything she does work-wise as she never wants to have to hand her over to a nanny."

It was reported earlier this year that Lily was adjusting to motherhood perfectly. The star has suffered with depression in the past, and was worried about how a little one would affect her lifestyle.

"Lily can't believe how perfect things are. She was anxious she might get post-natal depression because of her history, but despite being exhausted, she's on a total high," a friend of the star said in January.
