'They both like each other a lot,' says a friend...

Jessie J and Tinie Tempah are secretly dating, according to sources.

The two are said to have spent time partying together and are now an item. The pair apparently hit it off while performing together at last year’s Teenage Cancer Trust show at London’s Royal Albert Hall.

According to the Daily Mail, a friend of Jessie J said:

Jessie started going over to see Tinie at his place when they had a day off and one thing led to another. They both like each other a lot.

A source has also been quoted revealing that “Jessie has admitted to a few friends she has a secret boyfriend at the moment, but she has been keeping it close to her chest.”

Jessie J and Ed Sheeran are said to be recording a duet together, as Sheeran told the Daily Star Sunday “Jessie and I are talking about a duet. I don’t want either of us simply to feature on the other person’s song. I want it to be a genuine collaboration where we both sing equal amounts.”
