Lauren's mother is named Suzanne and her father, Sib, was the drummer for the famous rock band Boston. He replaced original drummer Jim Masdea in 1975 and played with the band until the early '80s. Sib died at age 67 after suffering a heart attack while performing on board a cruise ship in March 2017.
Lauren paid tribute to her father on Instagram the day before her wedding. Along with an old family photo, she wrote him a heartfelt message. "Dad, I miss you everyday, I love you and wish you could be here to see all of this too . . . But I know you have the penthouse view now," she wrote. "Thank you for still being with us & walking with me in your new way... We ❤️ YOU 🙏🏼."
