The 35-year-old actress posted a photo of herself and Vin Diesel on Instagram, along with a touching caption directed at Paul.
"Ride or Die through thick and thin, 15 years later surreal to think we made it through such a tough painful production," she wrote. "But this one's for you P I hope we make you proud love you."

Michelle posted a similar message on Twitter, calling filming "the hardest emotional roller coaster", and thanking those who had worked on the movie.
"Mad love to the fast crew for a labour of love and respect to a legacy that will live on long after we're gone. One Love".
The Fast & Furious crew posted an open letter on their Facebook page, acknowledging the difficulties they faced in continuing following Paul's untimely death in November.

"We made it. Today we completed the last shot in the production of FAST & FURIOUS 7," read the letter. "There was a time when we didn’t know how we could go on, or even if we should. But we listened to you, and you inspired us not only to keep going but to try and make the best FAST & FURIOUS movie yet.
"Our FAST family has been together for almost fifteen years now and has grown a lot in that time. From the start, Vin has been our leader who feels what’s right for FAST in his gut and in his heart. When we had to stop production last year, Vin gathered us back together and moved us forward when we needed it most. He led us to this day."

The message also mentioned Paul's two brothers, who stood in for the actor after his death.
"Caleb and Cody joined us to honour their brother and help complete his work. Our family is big and strong but it won’t ever quite be whole again without Paul."
Fast & Furious 7 is due for release in Spring 2015 and the open letter ended on a positive note saying "The countdown to April 3 begins".
