keanu reeves alexandria grant

In Hollywood, there seems to be an unwritten rule that older, famous men must have relationships with women who are 20 to 30 years younger.

These May-December romances are so common that they're almost laughable.

Dennis Quaid, 65, recently revealed he is engaged to Laura Savoie, 26.

Comedian Dane Cook is dating 20-year-old singer Kelsi Taylor.

And, of course, Mick Jagger, 75, is currently seeing 32-year-old ballerina Melanie Hamrick.

The heart wants what the heart wants, so who are we to judge? But it's refreshing to see a man in Hollywood date a woman his age. That's why people are pretty excited about Keanu Reeves, 55, and his girlfriend artist Alexandra Grant, 46.

Grant's work explores the use of text and language in various media, including sculpture, drawing, photography, and painting.

The two were photographed holding hands on the red carpet at the LACMA Art + Film Gala on Saturday.
