For ten years, Stacy London and Clinton Kelly were the perfect pair as they ambushed unsuspecting fashion criminals, who have been nominated for a makeover by their family, friend, or colleagues.

London and Kelly showed off their undeniable chemistry and incredible styling skills on TLC's What Not To Wear week after week, until the show ended in October 2013.

Both London and Kelly have since taken up other responsibilities. London is the Editor-at-Large of Shape Magazine, and the host of the TLC show Love, Lust, or Run, which is similar to What Not To Wear. She has also authored two books, including a memoir titled The Truth About Style.

Kelly also has some writing credits to his name, including the recently published series of essays titled I Hate Everyone, Except You. He is now the moderator of the ABC daytime cooking show The Chew.

Although London and Kelly continued to work in fashion and TV, they didn't hint at working together again. Many fans presumed that they were waiting for the right opportunity to come knocking, but that is a far cry from the truth.

During a recent episode of The Chew, Kelly revealed that he and his former co-host aren't on the best terms, in fact, they aren't talking to each other at all.

Kelly told his current co-hosts that London had blocked him on Twitter, and he did not realize it until some tagged them both in a tweet, and he wasn't able to access London's page. He posted a screenshot of the message that showed up when he tried to reach London's profile, with the caption "Alllll righty then."

His Twitter followers didn't waste any time responding. Many were disappointed to find out that their favorite TV pairing are no longer friends.

The TV host later replied to some of the questions, telling one user, "Don't go spreading out-of-context bulls"“t" after they implied that Kelly started the feud by speaking ill of London in his book.

Kelly, who once compared his casual and fun relationship with London to "a brother and sister in the backseat of a car on a long car trip," said that he didn't share this piece of information to get attention, he simply thought it was "hilarious."

When asked to reveal more details about the situation between him and London, he said that it is "old" news.

"The tea is old. And I never spill tea unless I'm shook, which I'm not," Kelly tweeted.

Kelly did hint that there was some tension between him and London in his book, which was released earlier this year. He said that they hadn't spoken in a while.

"We spent so much time together for 10 years ... It was funny in the beginning when we completed each other's sentences, Kelly told American-Statesman, adding "but it got to be like, "˜OK, we need a break from each other.'"

In an interview with the Connecticut Post, Kelly said he did not have any regrets spilling behind-the-scenes secrets in the book.

"We loved each other and despised each other, and if she were writing a book, I expect she would say exactly what she thought about me too. And it would be fine," he explained.

London has yet to offer comments on the situation, but she has previously admitted that she can be difficult to work with.

"Has anybody ever gotten mad at me? Are you talking about guests or are you talking about the crew?" she told People a while ago. "Everybody got mad at me, oh yeah. I piss everybody off."

Well, she was not kidding. After all, she did piss Clinton Kelly off.
