LANCO Frontman Brandon Lancaster and Wife Tiffany Welcome Second Baby: 'So Much Excitement' (Exclusive)

Brandon Lancaster's family is growing again!

The LANCO frontman, 34, and wife Tiffany have welcomed their second baby, a rep for the couple confirms to PEOPLE exclusively.

Son Ezra Keith Lancaster was born on Monday, Sept. 18, at 7:25 a.m., weighing 6 lbs., 8 oz., the family shares. The baby boy joins big sister Elora Ivelle, 3.

"Tiffany and I are thrilled to welcome our second child, Ezra Keith Lancaster, into the world. I am just so thankful for my wife, who has given me the best gifts in my life — and she did it again with Ezra," Brandon tells PEOPLE.

"His name is special to us for a couple reasons — Keith is my father’s name, and Ezra means 'God helps' — if I could only pass on one lesson to my son, it would be to always look to God, and his name will forever be a reminder of that."

The couple is relishing that there's "so much excitement and joy in our family right now."

"It’s been a whirlwind of a week, to say the least. Tiffany and I celebrated our anniversary on the 17th, Ezra was born on the 18th, and our daughter, Elora, turned 3 on the 19th," the new dad of two shares.

"Elora is overwhelmed with happiness at having a little brother. Even at 3 years old, we can already tell she’s going to be the best big sister," he says.

Of their decision to keep this pregnancy quiet, Brandon explains, "We didn’t intend to keep this pregnancy under wraps initially, but the longer we waited to share it, the more we enjoyed getting to soak in this special time as a growing family together, so we chose to wait until his arrival to share the news."

Brandon tied the knot with Tiffany in September 2017 during an intimate sunset ceremony outside Nashville, Tennessee, surrounded by 200 of their closest family and friends, a rep for the singer told PEOPLE in a statement.

The ceremony was filled with personal touches throughout. Tiffany walked down the aisle to Coldplay's "Til Kingdom Come," while Brandon stood next to his groomsmen including LANCO bandmates Chandler Baldwin, Tripp Howell and former members Jared Hampton and Eric Steedly.

The group will kick off their headline ‘Run, Run, Baby’ tour in Nashville on Oct. 2, in support of their forthcoming ‘Run, Run, Baby’ EP, which drops next Friday and is currently available for preorder.

The project marks the band’s first project release since 2021, not only offering the perfect, all-encompassing introduction to a new, musical chapter in LANCO’s career, but also serving as their debut project under Riser House Records.
