Clinton Kelly had a bemused reaction to Stacy London blocking him on Twitter.
Kelly posted a screenshot for his 241,000 followers after London blocked him on Twitter. The photo showed how he is "blocked from following @stacylondon and viewing @stacylondon's Tweets."
"Alllll righty then," he wrote.
London, who has 194,000 followers, had recently responded to a fan comment about "What Not to Wear," but has yet to explain why she blocked Kelly.
Kelly and London co-hosted nine seasons of TLC's "What Not to Wear" series, which ended in 2013.
Kelly, who now hosts "The Chew," told fans Thursday his feud with London is "old."
"The tea is old. And I never spill tea unless I'm shook, which I'm not," he wrote.
Kelly previously hinted at tension with London in his book "I Hate Everyone, Except You" which debuted in January.
He told the Austin American-Statesman at the time that he hadn't spoken to London in years.
"It was funny in the beginning when we completed each other's sentences. It got to be like, 'OK, we need a break from each other.'"
