Donald Trump may be president-elect, but Alec Baldwin is not in a position to play him on "Saturday Night Live" every weekend.

The 30 Rock star revealed to Vanity Fair at the annual American Museum of Natural History gala on Thursday night that he will appear on this weekend's show to portray Trump as the elected president for the first time... but won't be making a habit of it.

"I'm going to do it again this weekend, but not all that often. There was a lot of things online that was said about it -- like why didn't I do it after the election?" the 58-year-old actor explained. "I was booked that weekend. Not even other jobs; we have things to do. It crashes every weekend."

And then there's the issue of Baldwin's three children with wife Hilaria -- 3-year-old Carmen, 17-month-old Rafael, and 2-month-old Leonardo.

"When he does SNL, it takes a big chunk out of it because you're up so late, and then it eats into the next day," Hilaria shared. "And for us, with little kids, it's hard."

That's valid. Still, we are looking forward to seeing what the actor does with the Trump role this weekend.
