The couple showed no signs of jet lag as they were pictured coming out of the swanky 34 restaurant in Mayfair, London.

We couldn't help but notice just how happy Pharrell looked too, and we're hoping it's because he's going to be spending a lot of time in the UK in the next couple of months!
In the summer, the 41-year-old will be delivering his chart-topping hits at this year's Capital FM Summertime Ball in June, and he'll be performing at the Wireless Festival in July.
This week, 'Happy' hitmaker Pharrell also announced two UK dates as part of his 'Dear G I R L' European tour, in which he'll be heading to Manchester (9 September) and London (9 October).
It's also been a pretty successful year for the singer and producer, who released his chart-topping album G I R L in March, and was behind two of last year's biggest summer tracks, Daft Punk's 'Get Lucky' and Robin Thicke's 'Blurred Lines'.
Despite being in the music industry for more than 20 years, Pharrell's recent heightened success has left him feeling rather overwhelmed.
During a tearful interview with Oprah Winfrey in April, Pharrell explained: "It's overwhelming because I love what I do and I just appreciate the fact that people have believed in me for so long that I could make it to this point."
Later this year, Pharrell will also be joining The Voice US as a new coach.
