TikTok has attracted quite a few high profile names to join of late. Director Martin Scorsese made a gas debut on his daughter Francesca's profile, while Cher joined TikTok for Pride month, and Avril Lavigne's debut involved a collab with Tony Hawk.

Now Ryan Reynolds has joined TikTok and naturally, he was going to make his first post a funny one.

Yesterday the actor posted a a video showing him lip-syncing to "I Swear," by All-4-One.

Those who have been following his acting career will recognise that it's a callback to what his character Chris Brand did in 'Just Friends'.

The 2005 rom-com saw Ryan Reynolds play a formerly overweight dork who returns to his hometown a hit record producer.

He tries to start a relationship with his BFF and crush (Amy Smart) who has always considered him just a friend.

Here's the "I Swear" bit.

And here Ryan Reynolds recreates the lip-sync, complete with dramatic looks to camera and passionate hand gestures.

"I swear you will be disappointed by this account," he captioned his video.

They're not the only posts Ryan Reynolds has graced your TikTok timeline with.

In one his character of 'Deadpool' dons a Wrexham Football Club shirt and another video includes Rob McElhenney, who has invested in the club alongside Reynolds, and also just joined TikTok.

There will be no duets, @rmcelhenney

It's perhaps worth noting that TikTok is a sponsor of Wrexham Football Club...
