Rob Lowe says Prince Harry and Meghan Markle didn't use his home for their Oprah interview, and thinks it was really at the TV icon's house

• Rob Lowe believes Meghan Markle and Prince Harry filmed their tell-all interview at Oprah Winfrey's house.
• Lowe, who also lives in Montecito, said people thought the chat was filmed at his home.
• Winfrey has only said that the interview was filmed at a "friend's" house.

Meghan Markle and Prince Harry spilled plenty of secrets during their tell-all interview with Oprah Winfrey back in March, but the location of their sit-down chat was kept under wraps.

But Rob Lowe believes it was shot at Winfrey's house all along.

Lowe recently discussed how life in his neighborhood of Montecito has changed since the Duke and Duchess of Sussex moved in, revealing that many people thought Markle and Harry met with Winfrey at his home.

"It's so funny, everybody thinks the interview was shot at my house, and then my friend Ted Sarandos, who runs Netflix, everybody thought they shot it at his house," Lowe told the hosts of E! News' talk show "Daily Pop" on Friday.

"Here's my thing - and I have no idea, I have no idea - I think they just plain old shot it at Oprah's," he added. "I swear to you. And I think they just said it was at a mystery location."

During the interview, Winfrey said that the trio weren't filming their sit-down at Markle and Harry's home in Montecito but rather at a "friend's house."

Winfrey - who owns up to 70 connected acres in Montecito valued around $86 million - did not specify who the "friend" was during or after the interview.

The Santa Barbara, California, neighborhood is home for many A-list stars, including Gwyneth Paltrow, Julia Louis-Dreyfus, and Ellen DeGeneres.

But Lowe said there's been a lot more interest in the neighborhood since Markle and Prince Harry moved in.

"They definitely have brought a lot of attention to my sleepy little town," Lowe, who has lived in Montecito for the last 26 years, told E! hosts Kym Whitley and Justin Sylvester.

"Let me tell you something: Once the royals move into your neighborhood, the neighborhood is never going to be the same," he added.

Lowe noted that Markle and Harry "keep a low profile," but said it was only inevitable that there would be more interest with the royals in town.

"When Oprah moved in, that began the sort of resurgence of Montecito," he continued. "And now that the royals are there [...] the good news is property values go up, the bad news is the lines are longer at Starbucks."

During their sit-down interview with Winfrey, Markle and Harry said they had stayed at Tyler Perry's mansion in Beverly Hills before purchasing their home in August and settling down in Montecito with Archie.
