Judi Dench, 87, and her grandson Sam are joined by Louis Theroux for an amusing TikTok dance

They went viral during the Covid-19 lockdown for their fun TikTok videos.

And Dame Judi Dench and her grandson Sam Williams have returned with their entertaining clips after swallowing Louis Theroux to do a TikTok dance with them.

The legendary actress, 87, and her grandson, 25, were joined by the documentary filmmaker, 52, as they showed off their dance moves in a coordinated routine.

In the video, shared on social media on Tuesday, Judi’s daughter Finty Williams, 50, was also seen participating in the dance in their garden.

As the music played, the group was seen joining the TikTok dance craze raising their arms above their heads and wiggling their hips.

Judi cut a stylish figure in white pants and a matching shirt, while styling her white locks in a tousled style and showing off her moves.

Her grandson Sam, who was mistaken for Ed Sheeran in the past, kept it casual in black jeans and a white T-shirt, worn under a red checked shirt.

He tucked his red locks under a navy blue baseball cap and smiled broadly when he seemed happy to have his grandmother make another TikTok video.

Judi’s daughter Finty looked effortlessly chic in a forest green midi dress and a pair of black boots when she got involved in the craze.

Meanwhile, Louis looked suave in gray slacks and a dusty blue shirt, which he styled with a pair of beige Chelsea boots to complete his look.

Judi was recently featured in an episode of his new series Louis Theroux Interviews, with the star likely snagging him in her TikTok video while they collaborated on the show.

It was part of a new six-episode series in which Louis interviewed singer and songwriter Stormzy and adventurer Bear Grylls, among others.

Their latest funny dance clip comes after Judi and her grandson regularly went viral on TikTok for their videos during the lockdown.

Last May, Judi spoke about the decision to join Sam for the fun videos and admitted that he is “very strict” about her performances.

Judi and Sam appeared on This Morning and talked about filming the videos together, with the latter saying his grandmother was “quite hesitant about TikTok at first, but after a few videos she was ready.”

Judi said of Sam’s directions for the videos, “Strictly! Very strict. I’d say “we’re doing it now” and he’d say “no, you can’t do it, now you’re not good enough, do it again, do it again!”

‘We were lucky. Finty [her daughter] wasn’t with us, but Sammy and I were very lucky to be together. Thank God for the phone and FaceTime.’

Judi’s grandson bears a remarkable resemblance to singer Ed Sheeran, so much so that the musician sent his security to help Sam when he was harassed by fans who believed he was the Shape Of You hitmaker.

“I got the front and everyone around me went crazy,” Sam said earlier. “I saw him a few days later and he said, ‘Oh, I saw you were busy, so I sent my security for you,’ so nice of him.”

In February, Judi went viral after starring in a hilarious TikTok game with Sam where she had to finish the lyrics to popular songs.

“I’m going to read you a text, you have to finish the next one,” Sam told the legendary actress, moaning in horror.

Kicking off with Jason Derulo’s Let me Take you Dancing, the national treasure revealed: ‘I like Jason Derulo.’

But Judi’s fondness for the Get Ugly hitmaker wasn’t enough for her to get the right answer.

“Let me dance with you…” the Skyfall actress’ grandson urged her, to which she replied, “… You have nothing to do tonight.”

As they both burst out laughing, Judi tried to defend her poetic but incorrect response.

“That’s actually a pretty good sentence,” she said.

Then the star’s grandson questioned her about Ed Sheeran’s hit Castle on the Hill.

“You’d better get this one right,” her relative warned before reading the line, “Sing to Tiny Dancer….”

“…Tiny Dancer sings to me,” Judi replied before casting a straight side eye at the camera.

And Judi took offense with the last song in the game, Sucker from the Jonas Brothers.

When her grandson revealed the correct lyrics were, “I’m a sucker for you.” You say it and I go everywhere blindly,’ she replied: ‘That doesn’t rhyme!’ while her grandson looked on in annoyance.

Viewers on TikTok went wild for the national treasure: “You can’t just put Dame Judi on my For You page like I have to prepare,” said one.

“If Dame Judi Dench says it doesn’t rhyme, IT DON’T rhyme SAM,” commented another.
