Big Brother UK host Emma Willis has confessed she's "completely terrified" ahead of her debut tonight.
The new series of Big Brother launches on Thursday night on Channel 5 and it'll be Emma's first time in charge.
Having previously hosted spin-offs Bit On The Side and Little Brother, Emma replaced Brian Dowling last month as the main presenter of the Channel 5 show.
But she admitted this week: “I did have reservations. Big Brother is a show I’ve always loved and it’s a huge deal for me to take over as presenter, but I was apprehensive at first as I didn’t want to leave Big Brother’s Bit On The Side.
"Another reason was Brian. Luckily, he was very sweet and decent about it all because that’s the sort of person he is. We both know this is the way the industry works.”
But even with Brian's blessing, Emma admitted she was worried about stepping into Davina's shoes, as well as facing millions live on telly.
While on Bit On The Side Emma could - in her own words - "swear and move on", the main show will require a somewhat more professional approach.
She told The Sun newspaper: “I’m completely terrified. Davina was my first real idol and the best presenter on the telly when she did Big Brother.
“I’ll have to wear heels and a dress while I’m presenting, and I’m scared I’m going to fall over. I can’t stop thinking about it.
"But this is the job of my dreams, I’m a Big Brother obsessive, so I just think: ‘Bring it on.’”
Big Brother 2013 airs tonight on Channel 5.
