The One Show host Adrian Chiles is said to be unhappy about losing his Friday slot to radio presenter Chris Evans.
Currently on holiday for the Easter break, Adrian is angered that news of Chris' new job has been announced while he is away, the Daily Star reports.
"Adrian is not pleased this has been announced while he's on holiday. He feels it's a stitch-up," a source tells the newspaper.
Adrian was previously believed to have told BBC bosses that he would quit his post altogether if flame-haired Chris was hired, and he did not want to be a "warm-up act".
Meanwhile, 44-year-old Chris has confirmed news of his post through Twitter.
"Story about The One Show in les papiers, tis true!" he wrote.
