South London singer-songwriter Jessie Ware may not be mainstream yet, but she already has a growing number of celebrity fans.

Jessie revealed Tinie Tempah had been in touch to say he liked her song, 110%.

Hollywood actor Russell Crowe has also tweeted about the same song and posted a few of her music videos on his profile.

The Mercury Music Prize nominee has even caught the attention of Katy Perry.

"I accidentally met her and she said she worked out to my music, so that was cool, that was really cool," Jessie said.

She added: "She looks great! I'm glad I'm helping her look that good."
