And now none other than Jessie J has declared her love for the boys.

The band have already got the support of fellow boyband The Wanted and Mollie King form The Saturdays.

And now uber cool Jessie has given them her love too.

Lawson - that's Adam, Andy, Joel and Ryan - hit the stage at a jazz festival in Switzerland last night, where they supported Jessie J.

And afterwards Andy took to Twitter to declare how brilliant he thought the British singer was.

He posted: "Us and the amazing @JessieJ she was incredible tonight!" alongside a snap of the five of them.

But it wasn't long before Jessie returned the compliment, retweeting Andy and tweeting: "You guys rocked! See you tomorrow ;)"

Joel piled in on the gushing about the songstress, posting: "Also... @JessieJ is one of the best artists of our generation... Wow ‪#Fact"

Naw.

And it looks like the gang celebrated their performance with a few drinks, with Ryan posted: "All good nights end up drunk with Jessie J".
