Think the Star has taken Steven's tweet and twisted it out of proportion. He doesn't specifically say he's presenting, just attending rehearsals - he could be rehearsing panel discussions, opening skits, one-off VTs etc.

Also, IIRC, Steven lives quite close to Elstree, so if they need someone as a guinea pig guest for rehearsals he'd probably be among the first choices

Bit On The Psych has been axed so there's no need for an Iain Lee anymore, and Luisa already fills the regular panellist/roving reporter role
