It’s one small step for mankind, and one giant leap for Lady Antebellum’s Hillary Scott.

The country star took to Instagram this week to let fans in on a major milestone for daughter Eisele Kay.

“Our 13-month-old daughter started walking on what we thought was going to be just another Wednesday,” she captioned a photo of herself with hubby and Lady A drummer Chris Tyrell. “We are 50-percent happy and proud, and 50-percent sad it’s going so fast. And yes, I cried. A. Lot.”

Baby Eisele, who shares a birthday with royal baby Prince George, is the first tiny tot addition in the trio.

Hillary’s bandmate Dave Haywood and wife Kelli are expecting their first little one before the end of the year.
