Jay Leno returns to 'Tonight Show' as guest

Former "The Tonight Show" host Jay Leno will return to the evening talk-show, now hosted by Jimmy Fallon, as a guest.

According to a spokesperson, the comedian will appear alongside Lucy Liu and Kevin Delaney on Friday, reports variety.com.

Leno left the show in February this year after hosting it for nearly 22 years.

However, this will not be Leno's first time on the show since Fallon took over the reins. He earlier made a contribution to a skit.
