He's the beloved frontman of 80s band Madness.
But TV viewers were left unimpressed when Suggs made a guest appearance on Channel 4's Sunday Brunch, this weekend.
The 57-year-old was branded "rude" by viewers, who unanimously panned his presence on the weekly cooking programme.
Specifically, they chided him for being disrespectful to both the presenters and fellow guest Olivier Ward from Gin Foundry.
Taking to Twitter to air their annoyance, countless people shared their opinions of the former chart-topper.
"Love @SundayBrunchC4 but Suggs is so annoying and rude. Had to turn off," one said. "Where’s Bradley Walsh or Joe Lycett when you need them?!".
Another quipped: "Suggs owes that gin bloke an apology for how he just treated him. Absolutely no need to be rude."
Agreeing, a third added: "Definitely won’t be tuning in again if Suggs is back on. Interrupting and trying to be funny, but just cringe-worthy and rude!".
A fourth simply posted in angry, upper-case letters: "PLEASE NEVER HAVE SUGGS ON AGAIN".
However, some people seemed to enjoy his contribution, even though he appeared to be a little worse for wear.
One person risked overstatement by describing his appearance as "legend", while another posted: "Suggs is actually funny".
Randomly, another declared: "Got to say Suggs is looking good".
