Louisa Lytton shared a heartwarming video of her Grease musical co-star Tom Parker rehearsing.
The Wanted singer died last week aged 33 following a two-year battle with brain cancer.
Louisa, 33, and Tom performed together as Danny and Rizzo in the 2017 touring production of the musical.
In the clip, Tom was dressed in his T-Bird get up - a leather jacket, white t shirt and black trousers with a belt.
Singing the start of the song, he belted: "Systematic, hydromatic, why it's Greased Lightning!"
Clearly chuffed with his performance and he exclaimed: "Oh my god I nailed it. I nailed it didn't I?"
Louisa tagged Tom's wife Kelsey and wrote: "Nailed it mate [heart] all of it."
Tom, who told Hello! magazine that he put his wedding on pause ahead the Grease tour.
He said: "We wanted to make sure we plan it right and I don't want to take two weeks off, get married, do a week on honeymoon, then go back on tour. I didn't think that was something I'd be comfortable with.
"I feel like the wedding is the girl's day and her dream. I feel like that might be seen as a cop out, like I don't want to do much, but I’ll roll with that.
"I mean, Kelsey knows what she wants and how she wants it to be, so I’m letting her put everything into place and I’ll just give her my credit card when needs be."
Since his tragic death, Kelsey has raised more than £30,000 for "amazing causes" in Tom's name.
She started a GoFundMe page on Saturday to "Keep Tom's memory alive forever".
She said: "We simply couldn't have got through the last two years without the help and support we have received, and if we can offer it back to others, that would be the best way to honour Tom, and make our two children - Aurelia and Bodhi - proud."
On Wednesday she broke the news that Tom had passed away.
Sharing a black and white photo of her husband, she wrote: "It is with the heaviest of hearts that we confirm Tom passed away peacefully earlier today with all of his family by his side.
"Our hearts are broken, Tom was the centre of our world and we can’t imagine life without his infectious smile and energetic presence.
