Much like his job in Severance, fans have declared Adam Scott's youthful visage as somewhat mysterious.

Many were shocked to find out the Parks and Recreation actor is not only in his 50s - but married and a father to two teenage children.

The 52-year-old surprised TikTok users when he made an appearance in his 16-year-old daughter Francesca's video - with fans swearing he's not old enough to even have kids.

In the short clip, Francesca was lip-syncing to an audio clip of Kim Kardashian talking to her then brother-in-law Scott Disick, listing off things she was doing on the weekend.

The video began with the teen lip-syncing: 'I have a busy week.' 

The camera then panned to Scott, who looked unimpressed as he lip-synced Scott Discik's part, asking: 'Do you?'

'Thursday, Nobu. Vegas, Friday. Then I have a spray tan at 8.45,' Francesca continued, with it then switching back to Adam who says: 'Oh my god, things are filling up!'

'Me informing my dad about my weekend plans,' she jokingly wrote on the video.

Viewers were not only shocked by the actor popping up at the end of the video - but also by the fact that Adam was old enough to even have a teenage daughter. 

'It appears that I've severely underestimated Adam Scott's age,' one perplexed user wrote.

'What are you talking about Adam Scott has an adult daughter,' another wrote in disbelief. 

'What do you mean Adam Scott is your dad?' wrote another.

Someone else laughed: 'Not me thinking Adam Scott is like in his 30s.'

'Adam Scott has been 35 to me for the last 20 years. Paul Rudd level aging,' declared someone else. 

Another mused: 'I've really never thought about how old Adam was until now.'

The TikTok was also posted to Reddit, where users discussed how old they thought he was. 

'For five years I thought he was mid 30s,' agreed another fan. 'I saw this video and went Adam has a teenage kid?! Isn't he just mid 30s.'

'Ohhhh I thought he was in his early 40s!!' chimed in someone else. 

Adam married producer Naomi Sablan in 2005. In addition to Francesca - whom they often call 'Frankie' - they share an 18-year-old son called Graham. 

Adam has been working as an actor since the mid '90s, landing his breakout role as Griff in the hit sitcom Boy Meets World in 1994.

He is best known for his roles in Step Brothers in 2008, and playing Amy Poehler's on-screen husband Ben Wyatt in Parks & Recreation, after joining the cast in 2010. 

He's currently starring in the psychological workplace thriller, Severance. 

The popular Apple+ series premiered in February 2022 and followed Adam's character Mark Scout as he found himself at the center of an unraveling secret that forced him to confront the true nature of his work.
