Their rep confirmed the happy news to JustJared, and Curtis himself confirmed it during an appearance yesterday on WNBC in NYC.
The co-host of Around the World in 80 Plates and the actress already have an 8-month-old son, Hudson.
It sounds like Curtis will have some time on his hands to plan the wedding with his blushing bride. After all, his show is getting close to the end of its season. The finale airs at 10 p.m. ET this Wednesday!
