Big Brother host Emma Willis has posted an emotional farewell before the reality show's final episode.

On Twitter she said the show, which will be aired on Monday night on Channel 5, "is about celebrating a family member as far as I'm concerned".

"It's going to be a hard show, but a fun show," she added.

It comes after former host Davina McCall wished Willis and fellow presenter Rylan Clark-Neal a good send-off.

It was announced in September that the long-running reality show's 19th series would be its last.

Big Brother, which began on Channel 4 before moving to Channel 5, has seen a decline in ratings over recent years.

The final of the first series in 2000, the first of 11 series hosted by McCall, attracted 9.45 million viewers.

In contrast, the final of the most recent series, broadcast by Channel 5 in 2017, was watched by just 1.11 million.

Viewers will find out whether Cameron Cole, Cian Carrigan, Akeem Griffiths or Zoe Jones is crowned the winner when the last episode airs at 22:00 GMT.
