Cruel Intentions fans gushed Ryan Phillippe has 'still got it' as he showcased his ripped physique in a rare thirst trap in his sauna on Instagram on Thursday.

The Hollywood actor, 51, showed off his ripped muscles and tattoos as he went shirtless in his sauna. 

Ryan rocked a pair of shorts and wore a sauna hat which is designed to protect the head and hair from extreme heat.

He wrote: 'Is it possible to be in love w a sauna?'   

Fans went crazy over Ryan's first trap as they gushed he that he is still their 'childhood crush' after watching him in 1999's Cruel Intentions. 

They wrote: 'Lord have mercy; Still crushin' over here like it's 1999. Sir, you look the exact same; Oh my goodness;

'Childhood crush and still is!!!; What a gift to help us through this tax day; This man still fine as hell'.

It comes after Ryan enjoyed a father-son day out with Ryan Phillippe at a special screening of their TV series Motorheads.

The 22-year-old rising actor and Hollywood vet both looked handsome in fashionable outfits complementing their respective styles.

For his part, the New York University student donned a forest green collared sweater and matching slacks, adding black accents.

Meanwhile, Ryan — who shares Deacon with ex-wife Reese Witherspoon — looked great in a beige suit. 

Speaking with People ahead of the release last year, Ryan revealed his reaction when he found out his son might be cast as his brother in a series of flashback scenes.

'I was like, "Wow, okay," he recalled, adding, 'I didn't want to be an influence one way or the other, so I said, "Well, offer it to him, and see what he thinks."'

He continued, 'The whole time [in my head] I'm like, "Please do it. Please do it. I want you there with me." But I wanted it to be his own decision.'

In addition to Deacon, Ryan shares 26-year-old daughter Ava Phillippe with Reese, 50. 

He's also dad to daughter Kai, 14, with 35-year-old ex-girlfriend Alexis Knapp.

When Deacon told him he was taking the Motorheads role, he said, 'I was thrilled, because what that meant was he would come in and out throughout the production, and I would get to spend time with him.'

His son has been studying music in New York City since 2022. 

He explained, 'When your kids go off to college, it's really unsettling. It really leaves a deficit, a hole in your life in some ways. 

'Even though I go and visit him in New York, and we spend a lot of time with each other when we can, it's different than when you've got them in your house every day. This experience offered me that opportunity again to live together for a week.'

The proud parent gushed, 'I was there through his first night shoot, which was really funny to see him struggling to stay awake at 3:30 in the morning. Even though we didn't have scenes together, it was very much a shared experience.'

He said one memorable highlight of working with Deacon was when they sat in showrunner John A. Norris' office together to brainstorm what their characters' 'childhood would have been like.'

'Me and my son talking about what we were like as brothers is a very cool, unique thing to have happened,' he noted.

'And then the two lead characters of the show, Michael Cimino and Melissa Collazo, they play [Deacon's] kids. 

'There was a time where we all got together and had dinner and had laughs about that because he's younger than both of them, but he's their father. There was a lot of really, really funny and sweet moments.'
