Nicolas Cage’s son Weston is getting married Sunday to his girlfriend Nikki Williams.

The two were apparently engaged secretly two weeks ago, and only revealed their intention to tie the knot this week – on Facebook, no less. The couple plans to wed in a small, private ceremony in New Orleans. And, of course, Cage is expected to be there.

Weston, 20, is the front man for the black metal rock band Eye of Noctum. He is Cage’s son by ex-girlfriend Christina Fulton.

Williams, who is 22, reportedly had her hen party tonight; Weston’s bachelor bash is scheduled for tomorrow night. Let’s hope he doesn’t take a page out of dear old dad’s book. (Cage had a little too much fun in New Orleans last weekend, and ended up in the drunk tank.)

Weston’s had his own problems. On April 1, he had to get stitches for a gash on his arm. According to some reports, the injury was actually a knife wound he received in a “heated argument” with Williams. Cage’s reps have adamantly denied those rumors. Let’s hope that in this case, daddy’s spin-doctors are right. That would be a pretty rocky start for a marriage.
