Lily was spotted after arriving at JFK Airport and was all smiles as she chatted on the phone while picking up a fizzy drink.
The sight was a stark contrast from last week, when Lily was hospitalised in London after falling ill with repetitive vomiting.
While in hospital, the mum-of-two had posted a selfie on Twitter which showed her hooked up to a drip and looking rather green around the gills.
"I can't stop projectile vomiting, also temperature #poisoned," she told her followers.
Thankfully, it appears Lily has fully recovered and is back to her old self as she embarks on another trip in Manhattan.
Days before falling ill, Lily was in New York to attend the Met Ball Gala - where she met Kanye West - and she was also in the Big Apple back in March.
After touching down in the early hours of today (13 May), Lily announced some exciting news for her stateside fans - a tour of America!
Kicking off in September, Lily will perform 19 dates in places such as Florida and Texas. And of course New York, which is fast becoming Lily's second home!
