The country legend took to Twitter in order to wish her husband a happy birthday, automatically winning the title of Hot Girl Summer.

Sorry to say readers, but the worldwide treasure that is Dolly Parton has won Hot Girl Summer during the heatwave of 2021, so you might as well give up all hope of ever claiming the title.

Celebrating her husband Carl Thomas Dean's birthday, and honouring the pledge she took previously, the 75-year-old suited up as a Playboy bunny once again, playing homage to her now-iconic 1978 'Playboy' magazine cover.

She begins the video by saying: "Today is July 20. It's my husband Carl's birthday and you're probably wondering why I'm dressed like this. Well, I'm 75 and they don't have a magazine anymore but my husband always loved the original cover of 'Playboy', so I was trying to think of something to do to make him happy."

With 'Playboy' no longer in print, the country star created her own photoshoot just for her husband, because, as she says: "He still thinks I'm a hot chick after 57 years. And I'm not going to try to talk him out of that."

Uploading a video of herself as her husband's birthday gift, she captioned her post with: "It's always #HotGirlSummer for my husband, Carl [love heart emoji] Happy birthday my love!"

Here's the Dolly Parton Hot Girl Summer video in all its glory.
