Miley Cyrus Celebrates Dad Billy Ray's Birthday: See the Crazy Cake She Baked!

Miley Cyrus helped her dad Billy Ray celebrate his 54th birthday Tuesday night in typical Miley-esque fashion: while wearing what appears to be a unicorn pajama onesie and holding a homemade vegan cake.

The rest of the Cyrus clan — Trace, 26, Braison, 21, and Noah, 15 — were present as well, and the whole family was snapped on Instagram. “Dad of the year every year,” Miley captioned one of the photos.

And while we have no idea what’s going on in the photo that appears to show Billy cutting into a rock of some kind — Miley wrote that “dad turnt intoooo a geologisssst 4 his biiiiirrrrrfffffdayyyyy” — the vegan cake she made for him does look appropriately Miley. It’s Day-Glo and jammed with everything from pinwheels to pom-poms to rainbow sprinkles (the cake’s lone traditional element).

PETA recently named Miley its “Sexiest Vegetarian Celebrity of 2015” — maybe she can do a takeover of their site after she gets done hosting the VMAs on Sunday?
