Rebel Wilson looked like a bonafide popstar as she recreated an iconic Britney Spears look for her upcoming movie Senior Year.

The actress donned a shimmery green off-the-shoulder top and skin-tight trousers in homage to Britney's 1999 hit (You Drive Me) Crazy.

"Absolutely stunning darling, you look gorgeous dear!" exclaimed one follower. A second said: "Yass! So excited for Crazy, this is going to be epic!"

A third added: "You look absolutely amazing," and a fourth gushed: "I hope you're taking that outfit with you because you look adorable!"

Senior Year follows a cheerleader (played by Rebel) who wakes after a 20-year coma and returns to high school to regain her status and claim the prom-queen crown which had eluded her two decades earlier.

Rebel's sneak peek comes after she gave fans an update on her health journey during a Live Q&A on Instagram on Monday.

When asked how much weight she has lost, she replied: "I try not to keep track of it too much, but it’s like 70 pounds, 75 pounds, maybe a bit more. Which in kilos, my international audience, is like 30, 35 kilos, close to that."

She added: "So far have not gained any of it back, which is pretty cool, because never in my life have I been able to do that."
