During an interview with Ireland's RTE One, the "Shape of You" singer said he's had a Bond theme song ready to go for awhile.
"With Bond, I've actually had a theme tune written for about three years, just in case," Sheeran said.
The 26-year-old said he has not been asked yet and refused to say what it's called.
"I'm not gonna say, because someone might steal it. But it's good," Sheeran said.
Sheeran said he also had a song planned for a potential Eminem collaboration. He got to see that dream come true this year with "River," which appears on Eminem's Revival.
"So it's the same with Bond. If ever I'm called, I'll be like, 'All right. Here you go.'"
Sheeran might want to stay near the phone because he might get called soon. Bond producers Barbara Broccoli and Michael G. Wilson are putting together another movie with Daniel Craig as 007. It's expected to be Craig's final movie in the franchise.
Broccoli said in an interview in Ireland last month that she will announce more details on Bond 25 early next year.
