STRICTLY Come Dancing star Dan Walker accidentally let slip the show's closely-guarded schedule live on air.
The 44-year-old BBC Breakfast presenter revealed the dates the first show and live shows start this month.
Dan made the blunder on BBC One today after Louise Minchin revealed when she would be stepping down from the news programme.
Whipping out his phone and firing up his personal calendar, Dan said: "I was just going to put your date in the diary."
Then, looking through his Strictly appointments, he added: "I meet and greet the partner in a couple of days time.
"And actually the first show is on the 18th and then the live shows start on the 25th."
Louise replied: "Perfect, I leave on the 15th, you leave on the 18th."
But one fan laughed: "More news about strictly. now know when it's on tv AT LAST! Thanks Dan."

Dad of three Dan recently explained that he doesn't care about criticism because, as a devout Christian, he takes no value from what other people think of him.
He said: “I never mind what people write or say about me. That’s because, as a Christian, I don’t take my value from what people think about me.”
