Having three children (and a fourth on the way) has made Heidi Klum and Seal very educationally-minded these days.

And yesterday afternoon (September they were spotted at Bill Gates’ “Get Schooled” Los Angeles Conference and Premiere at Paramount Studios.

Ms. Klum looked preggers pretty in a black silk dress with black trousers and grey suede heels while Seal hid behind a pair of black sunglasses as they passed the paparazzi.

As for their ever-growing family, Heidi told press she’s planning on making this baby her last. “We’re outnumbered. Four is perfect. Three is a lot. But four? It’s a lot of work. We’re hands-on, and we feel like this is what we can handle.”

She also revealed that they’re having some trouble coming up with a name. “Because we know it’s going to be our last baby, it’s way harder. We’ve never had this back and forth before. Before it was like, ‘This is the name and that’s that.’ We’re going to wait until we see the baby and hopefully the light bulb will come on and then it’ll be like, ding-ding-ding!”
