Katy Perry has tweeted Adele is "a BOSS".

The pop star was taken with the British singer's reaction to her impressive Grammys haul last night.

Katy is a big fan of the London-born soul sensation, who won an incredible six trophies at this year's Los Angeles awards ceremony.

"@OfficialAdele show em how its done, like a BOSS. #cutestsweetestmostdeservingest [sic]" Katy wrote on her Twitter profile.

Adele herself had been expressing her excitement about returning to the stage on the social networking site.

The 21 singer has been recovering from throat surgery up until recently and had been put on a strict vocal rest.

"Ima be, Ima be singing at the Grammys. It's been so long I started to forget I was a singer! I can't wait, speak soon xx [sic]," she wrote on her profile.

Meanwhile, Welsh music legend Tom Jones believes that Adele would make an excellent choice to record the next James Bond theme tune.

Having been previously honoured with performing 007 theme tune, the crooner recalled how the song elevated his career.

"I was 22 when I did the Thunderball song and it changed my career and was a huge honour," he told British newspaper The Sun. "Not that she needs it but Adele would be the perfect choice for doing Skyfall."
