Sutta turned up to watch the You're Beautiful hit-maker's gig at the W Hollywood Hotel in Los Angeles earlier this month, and the stars are said to have partied together after the show. And onlookers claim the pair kissed during the glitzy bash, before leaving the party together.
A source tells Britain's The Sun, "They met up straight after James' gig and hit it off like a house on fire. James instantly hit the bar and was buying Jessica drinks and was clearly smitten."
"They only had eyes for each other and were snuggled up in a corner of the bar laughing and joking away all night. By the end of the evening and a few drinks later, they were snogging (kissing) each other's faces off and very touchy feely before leaving together."
