Chris Evans’ first One Show appearance looked doomed yesterday when it appeared TV bosses hadn’t booked any celebs. So Doctor Who stars Matt Smith and Karen Gillan agreed to come to the rescue.
Producers will be relieved the Matt and Amy Pond actress Karen were available at the last minute.
A showbiz agent told The Sun: “They've known for months that Chris Evans will be hosting the show this Friday.
"So we were quite surprised they were asking so late in the day if we had anyone who could appear on the show."
"Getting people at short notice in summer is tricky, so it was pretty odd for them to be getting their begging bowl out like that."
Radio 2 breakfast DJ will be presenting The One Show on Fridays with Alex Jones as his sidekick.
A One Show insider, who described the situation as "tense", said: "It was getting hairy. We were running out of time. Chris's first show was looking like being a disaster."
BBC chiefs are reported to be paying Chris £12,000 a show.
