Jennifer Lawrence offered some words of advice to Prince Harry ahead of his royal wedding to Meghan Markle.

During the "Red Sparrow" premiere in London, the actress was asked how the royal prince should deal with his soon-to-be wife, Markle. "You've got to deal with one of us now. How about that?" Lawrence said.

Lawrence is pertaining to her and Markle's profession as an actress. Lawrence shot to fame in the big screen in the "Hunger Games" movie series. Meanwhile, Markle catapulted to fame in USA Network's "Suits."

When prompted for some advice for Prince Harry as a married man, the "Joy" star was game enough to share her thoughts. "I don't know, I mean if she's anything like me she's always right," Lawrence said.

While Lawrence warned Prince Harry about his future wife, John Oliver warned Markle of joining the royal family. The comedian even described the family as "emotionally-stunted group."

"I would not blame her if she pulled out of this at the last minute," Oliver said when he appeared on "The Late Show with Stephen Colbert." "He's a Brit, he's marrying an American girl. You're British, you married an American woman. I don't think you need to have just seen the pilot episode of 'The Crown' to get a basic sense [that] she might be marrying into a family that could cause her some emotional complications."

Stephen Colbert quipped that the current generation of royals was nice. Oliver had second thoughts and reluctantly agreed.

"They're an emotionally-stunted group of fundamentally flawed people doing a very silly pseudo-job. That's what she's marrying into. So I hope she likes it — it's going to be weird for her," Oliver continued.

Meanwhile, Anne Widdecombe is "dubious" of Markle joining the royal family. The former MP doesn't approve Markle for Prince Harry because of her past.

"I'm just very dubious that somebody who has made her life in those sorts of films, been married before, comes over and has to become an active member of a very, very stuffy, traditional family," Widdecombe told Piers Morgan and Sussana Reid.

Widdecombe made headlines earlier after calling Prince Harry's fiancée a trouble while she was still competing at the UK's version of "Celebrity Big Brother." "I think she's trouble. Background, attitude, I worry," the former MP said about Markle.
