The Duchess of Sussex's mother does yoga in her back garden with Oprah Winfrey

However, the outspoken philanthropist is adamant that was never the case and she actually went round to Doria's home to do some exercise in the sunshine with her.

Speaking to 'Entertainment Tonight', Oprah explained: "She said: 'I love kumquats,' and I said: 'I have a kumquat tree! You want some kumquats?'

"So it was a basket of kumquats, people. For all of the people who said I am getting her gifts and I'm trying to bribe her for an interview, they were kumquats.

"If kumquats can get you an interview, I'm all for it! She's great at yoga, so I said: 'Bring your yoga mat and your sneaks in case we just want to do yoga on the lawn.' So one of the bags was a yoga mat and the other was lunch."

However, Oprah hasn't just made friends with Doria as she was also among the small list of people and celebrities who were invited to Meghan and Harry's big day.

The beautiful ceremony - which was attended by the likes of Queen Elizabeth, George Clooney and David Beckham - had the whole world in awe.

Oprah said: "It was more than a wedding, I thought. It was a cultural moment. And you could not be there or watching on television... and not feel that there was a shift that just happened in the middle of it.

"I think it's bigger than them and I think it bodes well for hope for all of us."
