The Dancing With The Stars contestant wasn't giving too much away when asked about his brother's nuptials.
He told OK! that Nick and Vanessa are still 'trying to figure out logistics'.
Drew also said he wasn't sure if his children will be able to make it to the wedding if it's abroad because of their young ages.
He said: 'Five and one is kind of hard to travel. So if we're going to the other side of the world, ahhh, probably not. We'll have to see what they come up with.'
But he did say the Lachey family is a fan of Nick's bride-to-be.
He said: 'Everybody loves her. They're both very fiery and competitive. She loves sports which is great for him. That fire and drive brings the best out of each other.'
