'Smile' hitmnaker Lily looked rather cheerful as she was spotted leaving the Chiltern Firehouse Restaurant in Marylebone on Tuesday night (15 April).
Lily had attended a private dinner, hosted by French fashion designer Jean Paul Gaultier, with the likes of Naomi Campbell and Jemima Khan.
The singer was pictured happily talking on her mobile phone, and looked effortlessly chic in black skinny jeans, a striped crop top and black leather jacket. She added a splash of colour to her outfit by clutching a pink quilted Chanel bag.
Earlier in the day, Lily was in Paris working hard on the promo for her new album Sheezus. Mum-of-two Lily was seen heading into NRJ Radio studios in Paris, France, and stood out in a leopard print coat and floaty white minidress.
Sheezus, which is Lily's first new album in four years, took a total of two years to make.
Speaking about the process to Rolling Stone this month, Lily said: "I started when my oldest child was seven months old and I wrote through a lot of my pregnancy with the second one. Nothing really came of that though, since my hormones were all over the place."
Sheezus is due for release on 5 May.
