Dolly Parton has shared a rare glimpse into her life and notoriously private relationship, with a sweet and very sexy birthday video for her husband Carl, proving the 75-year-old has definitely still got it!

The music legend shared the new video on Twitter on Wednesday, showing her dressed up in a revealing Playboy bunny outfit wishing her husband of 55 years, Carl Dean, a happy birthday. Parton graced the cover of Playboy in 1978 and was reportedly set to pose for the magazine again 40 years later, but as the singer reveals in the video the magazine is no longer in publication and so she took matters into her own hands.

“In the first one I was a little butterball. well, I’m string cheese now. He’ll probably think I’m cream cheese, I hope,” she says winking at the camera. “Anyway, I’m going to surprise him, going in singing to him in my little bunny suit.

“What do you think? Think Playboy oughta pay me for the photo shoot? I do!”

Fans loved the sexy video, with hundreds flocking to the Tweet to share their thoughts on how incredible the singer still looks. “Just when you think Dolly can’t get any better,” one commented.

“Dolly… Carl is [a] very lucky man I bet every day is his Happy birthday [being] with you. You look great for your age and I wish you both lots of love and hugs from Hull in the UK,” another said.

“Reckon Carl might have had a few heart palpitations in that chair!” another joked.

Parton and Dean have been married for 55 years, but the two have rarely been spotted out and about together with the singer revealing her reclusive husband is simply a homebody.  In a candid chat with Entertainment Tonight last year the country singer opened up about their unconventional marriage and revealed that some people have told her they don’t actually believe he’s real.

“A lot of people have thought that through the years because he does not want to be in the spotlight at all,” she revealed. “It’s just not who he is. He’s like, a quiet, reserved person and he figured if he ever got out there in that, he’d never get a minute’s peace and he’s right about that.

“I’ve always respected and appreciated that in him and I’ve always tried to keep him out of the limelight as much as I can. He said, ‘I didn’t choose this world, I chose you, and you chose that world. But we can keep our lives separate and together.’ And we do and we have.

“Our joke about the fact, when people ask me why it’s lasted this long, I say, ‘Because I stay gone’. And there’s a lot of truth in that — the fact that we’re not in each other’s faces all the time.”
