'One More Night' singer Adam was pictured holding hands with his gorgeous partner as they left Nobu Berkeley on Wednesday (10 September).
Adam, 35, and his bandmates are in town to headline this evening's iTunes Festival gig at The Roundhouse in Camden, London, supported by Matthew Koma.
They follow other major acts to appear this year including Pharrell Williams, Sam Smith, Calvin Harris, David Guetta and 5 Seconds of Summer.
Maroon 5 will no doubt be playing a string of classic hits like 'She Will Be Loved' alongside newer songs including 'Maps' and other music from brand new album V.
V is the fifth (as you might have guessed!) studio album by Maroon 5. 'Maps' was the first single released from it, with 'Animals' second.
Before jetting to the UK, Adam tweeted: "Just need to take a moment to thank @maroon5 fans for being the best fans on earth. Thanks for giving us the best jobs ever!!!"
No doubt Behati will be front row for tonight's big concert in Camden!
Adam and Victoria's Secret model Behati married at an intimate ceremony in Los Cabos, Mexico in July.
