Prince Harry promised to never stop courting Meghan Markle before they tied the knot.

The Duchess of Sussex reflected on the secret to her enduring relationship with her husband on Thursday’s episode of “The Drew Barrymore Show.”

While conversing with host Drew Barrymore, Markle shared a memory of babysitting for a father who had once advised her, “Meghan, when you meet your partner one day, I hope he will tell you the same words I told my wife when we tied the knot, which is, ‘I promise to always court my wife.’”

The As Ever founder, 43, said she passed on the words of wisdom to the Duke of Sussex, 40, when they started dating in 2016.

“He goes, ‘I vow to always date you,’” she remembered Harry telling her at the time.

Markle said the practice of continuing to court each other well into their marriage has kept the spark alive.

“I believe we share this bond because we are both dedicated to treating each other with the same love and respect as when we were in the early stages of our relationship before making a lifelong commitment — during the courtship phase when you can truly appreciate the beauty and happiness of that initial romance,” she remarked.

“That’s, I think, what keeps things really alive,” she added.

Markle admitted that she “did not expect” to meet her literal prince charming, telling Barrymore that “life is full of surprises.”

“I’m very lucky. I’m married to the funniest, sweetest, most charming [person] … and he’s an amazing father,” she gushed.

The former “Suits” actress said she “counts [her] blessings” because she has a partner who is “so supportive” of her.

Certainly, Harry has been supportive of Markle in her different endeavors since their wedding in 2018 and their subsequent decision to step back from their royal duties and relocate to California two years later.

Last year, Markle launched her lifestyle brand — originally called American Riviera Orchard but rebranded to As Ever — and this week she debuted her Netflix cooking show, “With Love, Meghan.”

Meanwhile, Markle has been by Harry’s side as he continues to run his Invictus Games for injured, sick and wounded military members and veterans.

The couple share two kids: Prince Archie, 5, and Princess Lilibet, 3.
