Mondays can be a drag, but Zac Brown Band bassist Matt Mangano had a remarkably hard-to-top one, welcoming his second son and third child to the world on April 23.

"Everyone give a warm welcome to the newest addition to the ZBB family, straight from the low end department, Mason T. Mangano," reads an official post from the Zac Brown Band Instagram account, showing off the proud parents with their brand-new arrival.

For those who need a bit of a closer look — Mangano added his own personal post, with a closeup of the new arrival, and noting "he's just perfect," while also assuring fans that mom Emily is "a total champion."

Little Mason joins big brother Elliott and big sis Maia. He also is part of a little clan of ZBB babies who have arrived or are still cooking so far in 2018, including Coy Boyles' daughter Millie who arrived in February, and Clay Cook's baby who will arrive sometime this summer.

Mangano, the director of Zac Brown's Southern Ground Studios, took over bass duties in 2014. The band will be undertaking a lengthy summer tour that begins in June.
