Josh Thomas entertains and is entertained by fellow celebs in Come Dine with Me.

''A CHANCE for him to dress up his beloved dog, John'', is how the press release bills Josh Thomas' involvement in Celebrity Come Dine with Me. ''They made me put my dog in a f---ing outfit!'' Thomas protests. ''Now I look like some crazy, lonely person who puts their dog in outfits all the time.

''It all started as a joke. I was in Thailand and I sent some outfits to my boyfriend so he could dress up John. Now we can't stop. It's like having our very own Suri Cruise.''

In fact, Thomas signed up to the program - his third celebrity cooking show, following Celebrity MasterChef and Celebrity Ready Steady Cook - to prove ''that I'm not a complete loser''. ''I actually think I'm quite good at cooking,'' the comedian says, ''and I like the idea of being good at something on television after four years of having no idea [as a team captain] on Talkin' 'bout Your Generation. I want to prove I do have some skills.''

The celebrity episode marks the start of the fourth season of Come Dine with Me, in which contestants compete to host the best dinner party. Thomas has three rivals: PR supremo and media commentator Prue MacSween; Dannii Minogue's former husband and footballer-turned-model Kris Smith; and model and actor Chloe Maxwell.

''If you ever get the chance to go to Prue MacSween's house, take it,'' Thomas says. ''Everything is white - everything - with a couple of gold details. There are statues of busts everywhere. There's a big window that overlooks the Sydney Harbour Bridge. And in front of that window is a white baby grand piano, which she does not know how to play. I didn't realise such a place existed.''

MacSween titled her event ''An orgy of rude food''.

''I was worried we'd have to eat dinner that was shaped like a dick,'' Thomas says, ''but it was normal food with bawdy conversation.'' During one dinner, MacSween tried to engage him on politics, despite Thomas' best efforts to change the subject.

''We have completely opposing viewpoints,'' he says. ''I just could not imagine the conversation ending with me going, 'You're right, Tony Abbott is a hero', or her saying, 'You're right, Bob Brown does have a good vision for Australia'.''

He was charmed by Smith's first-ever attempt at a dinner party. ''He still had the barcodes stuck to the bottom of the wineglasses.''

Much to the producers' delight, Thomas also changed John's outfit between each course, which he likened to Mariah Carey's constant costume changes in concert.

''Kylie Minogue is a much better reference for that joke,'' he says, ''but I was very careful not to mention any Minogues around Kris.''

Before shooting Celebrity Come Dine with Me, Thomas made a semi-autobiographical comedy called Please Like Me, due to air in February on ABC2. The script was written so long ago it included scenes of him kissing girls. ''After I came out, we replaced the girls with boys. And I did get to cast who plays my boyfriend, which is obvious because he's beautiful.''

While 2013 is set to be big year for the 25-year-old, a job on commercial radio is unlikely: the last time he spoke to Green Guide, he declared, ''I haven't heard a new or exciting idea on the radio in this country, ever''. The day after that appeared, Nova's Dave Hughes and Kate Langbroek hauled him on to their breakfast show to explain himself. ''Shut up!'' Thomas says now. ''You got me in so much trouble last time. I don't want to get told off by Dave Hughes again.''

Celebrity Come Dine with Me airs Tuesday, December 11, on all Foxtel LifeStyle channels.
