E4 marked Big Brother’s 20th anniversary with a series of festive episodes hosted by Davina and Rylan, 31 – showing highlights and memories from the axed reality series.
However, some viewers have contested that Brian was not shown after winning the second series in 2001 – as well as the Ultimate Big Brother show in 2010.
Brian also hosted Big Brother when he moved from Channel 4 to Channel 5 in 2011, before being replaced by Emma Willis.
Brian had suggested that he had not been invited to participate in the celebratory series – hinting that he had been snubbed when he replied to a Twitter fan earlier in the week.
One fan tweeted on Wednesday: “Although I absolutely love watching the older episodes of #BigBrother find it very strange that there is no mention of [Brian Dowling] as a presenter ?!
“Very strange considering his love and his presence in the series? ”
Brian then responded by writing, “You are not alone. In fact, at this point, it gets pretty funny. People are trying to rewrite history. ”
However, Davina rejected the suggestion with a tweet from her on Thursday evening.
She wrote, “Just an FYI. We asked @brianofficial to be part of the show. ”
She added, “He was the ultimate roommate !!!! It was obvious. ”
Big Brother’s best shows have already seen familiar faces from the show’s 19 seasons – and host Emma Willis also participated in a video session with Davina and Rylan during the two-week event.
