Duncan Jones, the son of late rock legend David Bowie, appears to have commented on Lady Gaga's special tribute at Monday night's Grammy Awards.

Should Lady Gaga Come Back For Season 6 Of 'American Horror Story'?

Jones did not tweet anything directly against Gaga, but his message after her performance at the Grammys is being taken as a diss.

This is literally the definition of "gaga," and the parts about being "mentally confused" and "irrational" are being interpreted as Jones slamming the pop star.

Jones has not made any follow-up comments on Twitter or elsewhere, but the response has been mixed thus far. Gaga's fans are taking him to task, while others are voicing their own negative opinions on her performance.

Check out the variety of reactions to the performance:

Gaga performed 10 of Bowie’s most notable songs, including “Space Oddity,” “Heroes,” “Fame,” “Let’s Dance” and more. The performance featured a lot of moving parts and utilized special Intel technology.
