The 36-year-old Dancing with the Stars hoofer, who’s now co-hosting the show, dated the 49-year-old media mogul from 2011 to 2013 – and recently said she made herself “smaller” and twisted herself into the type of girl she thought Seacrest wanted.

Hough said: “I had this insecurity…. and so I then started playing smaller. So I was malleable to fit into exactly what somebody needed me to be for them to be happy.”

“Truth is, it wasn’t a flaming romance. What they had was a glorified friendship, but he thought they had a deal to respect each other.”

The upcoming Wheel of Fortune host also split with Aubrey Paige, 26, in April after three years, and previously dated food blogger Shayna Taylor, 32, for eight on-and-off years until their breakup in 2019.

Although Seacrest’s first episode is scheduled to air on Monday, September 9, he and White began filming earlier this year – and she was said to be left “feeling like a third wheel” during production.

One source said: “They started taping in late May and Vanna has tried to give Ryan advice and show him the ropes.

“But Ryan is a control freak. He finally told her he’s doing things his way and he’s not trying to be Pat Sajak.”

The insider continued: “So Vanna is again relegated to the background, but now it’s not with Pat, someone she knows and loves, but a new guy, Ryan.

“It’s not that she doesn’t like Ryan, but her chemistry with Pat was just much more natural. With Ryan, it feels forced and she doesn’t want that to come across to loyal viewers – and producers fear the audience will notice it as well.”
