Child's play: Lily Allen takes to the stage in New York wearing a crop top and baby bottle patterned skirt
She's reinvented her image since becoming a mother to Ethel, two, and Marnie, one.
And Lily Allen reinforced the idea that motherhood has changed her by donning a baby bottle embellished skirt to perform a string of hits from her latest album Sheezus.
The pop star took to the stage at Terminal 5 in New York City on Tuesday night in her custom-made House of Holland outfit, which featured a pink feather trim and a sequined skirt.

The Smile singer is fresh from supporting Miley Cyrus on the US leg of her Bangerz tour and has clearly been taking inspiration from the controversial hit-maker's wacky costumes and set.
Lily finished off the look with a glitzy pink top featuring her name emblazoned accross her chest and matching pink stilettos.
At one point during the gig, she whipped off the jumper to reveal a jewel-encrusted crop top.

The skimpy top flashed a hint of her toned stomach and made the most of her slender frame.
The 29-year-old star - who is married to Sam Cooper - has spoken candidly in the past about how motherhood has changed her as a person and as an arist.
While the former wild child initially found looking after her daughters took up all her energy, she soon started to feel a renewed creativity.

She told France's NRJ Radio earlier this year: ‘I thought I'd be a really happy mum just sitting at home, playing with my kids, that was my dream.
‘I love my children, but I'm a very impatient, busy person naturally so two babies, neither of them can talk, it was quite boring!
‘I didn't realise how much of a creative person I am and that I need somewhere to put my creativity.’
Lily also admits she is more conscious of her image and lyrics now that she has a family.
