Big Brother's Bit On The Side tonight saw a very special housemate reunion.
On tonight’s Big Brother’s Bit On The Side, host Rylan Clark-Neal celebrated his 300th episode.
The surprises started when Emma Willis shocked Rylan with a montage of his 'best bits' plus clips from celebrity fans ranging from Lisa Appleton to Geri Halliwell.
Later, another surprise saw a huge array of past Big Brother housemates storm the set.
They included Jon Tickle, Eileen Daly, Rylan's husband Dan Neal, Jack & Joe Glenny, Georgina Leigh, Jackie & Charlie Travers and Kathreya.
And even they weren't alone as Big Brother 8's Chanelle and Ziggy reunited on the panel.
The pair had coupled up on Big Brother back in 2007 - the year Brian Belo won - but broke up in the house, with Ziggy telling her: "It's not you, it's me."
However they then got back together again before splitting up for good about six months after the series finished.
Chanelle previously revealed that the couple frequently enjoyed sex in the house.
"I know I’ve always denied that anything happened in Big Brother other than arguments and drama because I didn’t want to sound like the UK’s biggest slapper," she told Now magazine. "But now we’ve got Geordie Shore and The Valleys I feel totally OK being honest and saying we actually had sex every day for about three weeks."
Finally, Rylan was left close to tears after getting a video message from former Big Brother host Davina McCall.
Bit On The Side airs tonight at 10:30PM on Channel 5 with host Rylan Clark-Neal.
Big Brother 2017 continues nightly on Channel 5. The latest episode airs at 10:30PM on Saturday night.
