Due in late summer, the couple revealed their news on the red carpet at the Clive Davis and the Recording Academy’s annual pre-Grammy gala on Saturday night (2/9) when Hubbard bent down to kiss his wife’s growing bump.

A rep for the family also confirmed the news to PEOPLE. The outlet shared a photo of the couple’s first-born Olivia in the snow in Sun Valley, Idaho sitting next to a sign that reads “Only child expiring on August 19, 2019! I’m going to be a big sister!”
The Hubbards welcomed Olivia in December 2017.
Hubbard is in Los Angeles for the GRAMMY festivities as he and his bandmate Brian Kelley, and pop star Bebe Rexha, are nominated for their record-breaking collaboration, “Meant To Be.”
