Quite a mixed bag on tonight's show, but they're often the best ones.
First up, Mrs Brown herself, Brendan O'Carroll, will be on the couch for a chat alongside Harry Styles. Yep, random, 'ey?
Brendan will no doubt be talking about his recently launched Saturday night chat show, All Round to Mrs Brown's, while One Direction's Harry will be telling Graham about his newly launched solo career and will give an exclusive UK television performance of his debut solo single Sign of the Times.
Brendan won't be the only comedian on the couch as Graham will also be joined by the hilarious Rob Brydon, who will be talking about his new series The Trip to Spain, which sees him and Steve Coogan play exaggerated versions of themselves as they travel together.
Finally, Vicky McClure will be chatting about her role in police drama Line of Duty.
There they all are now...
