Patrick J. Adams doesn’t have 'Suits' co-star Meghan Markle’s phone number anymore (exclusive)

Even Patrick J. Adams doesn’t have the royal digits!

The 36-year-old actor opened up to ET’s Keltie Knight at the This Bar Saves Lives event in Los Angeles on Thursday about his former Suits co-star, Meghan Markle, who is preparing for her highly anticipated royal wedding to Prince Harry on May 19.

Adams, who was joined by his actress wife, Troian Bellisario, noted that Markle “doesn’t need any advice” in the marriage department -- and he couldn’t give her any tips even if he wanted to!

“I don’t even have her telephone number anymore!” Adams admitted.

Adams and Markle, 36, played love interests Mike Ross and Rachel Zane on Suits before both leaving the series after its seventh season, which is currently airing on USA.

Ahead of Markle's real-life nuptials, she is set to have a TV wedding and Adams teased what fans can expect.

“I don’t know what there is to tease,” Adams said of their final episodes. “I know it was one of the most surreal days ever. Meghan and I have been so close from the beginning of the show, so to finally get to that moment was really great. And to have the rest of the cast there and supporting and I think we shot – I think the only tease is that we were shooting it until about seven in the morning. So if you see some bleary-eyed people, that’s probably why.
