Los Angeles, April 8 (IANS): Actress Emma Stone has apologised to a fan, who earlier requested her to join him for a prom proposal inspired by her movie "La La Land". She says she wont be able to make it due to prior work commitment.

Jacob Staudenmaier earlier made a musical video and posted it over social media while requesting Stone to join him for a prom night.

The student brought the letter he got from Stone on TV show "Good Morning America"

"I have the letter right here," Staudenmaier said.

He then read Stone's statement: "Jacob, thanks for making the greatest proposal I've ever received. I can't tell you what an honour that was and how much I smiled through that entire beautifully orchestrated video. 

"I'm in London working, but I hope you have the best time at prom, and I'm grateful you thought of me. Thank You. P.S. I do see (Ryan) Gosling around the eyes. Love, Emma." 

Staudenmaier is a 17-year-old student from Scottsdale, Arizona. He rewrote the lyrics to "La La Land" musical opener "Another day of sun" for the prom proposal.
