Alison Hammond and Dermot O'Leary reminisce about their time on Big Brother

Ahead of the return of Big Brother tonight, Hammond and O'Leary reminisced about their time on the show.

Talking on This Morning, Hammond said: "Loads of memories. For me, it was like I was on holiday, a two-week holiday. 

"Because I'd just come back from being a holiday rep, I just did all the stuff I used to do on holiday with everybody in the house. So I just have such lovely memories.

"Breaking the table, remember that? And then I pretended I didn't break it even though it was on camera."

Both congratulated each other on how far they had come in the years since before O'Leary shared his memories from the show. 

He added: "It was such a brilliant period of my life and I loved it, I got to know everyone so well.

"The fact we were interviewing people that you spent such a short amount of time with, but such a concentrated amount of time, you just get so close to them."
