It was an "all time high" for Alex Gaskarth and Lisa Ruocco.

The All Time Low lead singer married his high school sweetheart and girlfriend of 12 years in a beautiful, intimate ceremony in Baltimore, a rep confirmed to People.

"We've felt like a family for so many years. This just makes it official," the couple said in a statement to the mag. "We are so lucky to not only be marrying our best friend, but to have family and friends from all over the world joining us to share in this day and celebrate with us."

The musician, 28, and his bride, an event producer with Union3 Event Productions, exchanged vows Saturday night in front of close family and friends, then headed to Copper Kitchen restaurant for a dinner reception.

The bride planned the event "from top to bottom," the rep said, and focused on the couple's great loves: music, wine, traveling — and each other, of course.

Congratulations to the newlyweds!
