Dr. Phil revealed he and his wife Robin McGraw celebrated their 38th wedding anniversary on August 14.

Phil McGraw, 63, tweeted alongside a photo of himself with his 61-year-old wife: “We make the best team.”

Dr. Phil also posted a video on Instagram, breaking down the momentous occasion.

“Thirty-eight years of marriage,” he wrote.

“Think about it. That’s 13,870 days – 332,880 hours. That’s a lot of smiles.”

In an interview with New You, Robin McGraw has admitted that friends find it strange that she never argues with her husband.

She told the magazine: “People cannot understand when we say we don’t fight.  They go “that’s just not natural, you’re lying! Couples fight.”

“But we don’t fight and it’s because we had a conversation early on and I told him that it’s not natural for me to be in a house where people are screaming and yelling – my parents didn’t do it, I don’t do it and I don’t want to live in a house like that.  He got it and has never raised his voice around me. We don’t fight.”

Robin McGraw added that she keeps the spark alive by flirting with Dr. Phil.

“Always flirt!” she said.

“A piece of advice I’d tell women:  Learn what your husband considers flirting and learn what makes your husband happy.”

Phil and Robin McGraw have two sons, Jay, 34 and Jordan, 28. Jay McGraw and wife Erica have also given them two grandchildren – a 4-year-old girl named Avery and grandson London, 3.

Despite her growing career and duties as a mother and grandmother, Robin McGraw says that Dr. Phil is her number one priority.

She advises other women looking to balance work and family life to ask their husbands: “<<What can I do for you? Tell me what you need from me, what you need to hear from me, what you need to see me do. I’ll do it>>.”

Robin McGraw also recommends checking in with one’s husband on a regular basis, adding: “Phillip always needs to know I’m proud of him and the loves to hear that I appreciate him.”
