As some of you may know, October 3 marks the date of the unofficial holiday, National Boyfriend Day. Joining in on the social media fun, California musician Ty Dolla Sign and his girlfriend, former Fifth Harmony member Lauren Jauregui, took a moment to appreciate and celebrate their relationship. 

The couple has been together for quite sometime after collaborating hit track, "Work" in Jauregui's Fifth Harmony days. Jauregui took to her twitter to post, "shout out to my amazingly loving, talented, thoughtful, love bug of a man. You are such a light in my life and I’m so grateful for you and it’s an excuse to tell u that online so happy #NationalBoyfriendsday @tydollasign." The love was not lost on the "Don't Judge Me" singer who responded with a sweet message. "I love you with my whole soul!" he wrote. "So grateful to be able to call u mine my heart. Yours 4 eternity," he added. 

Dola Sign and Lauren have proven that not only are they successful as a couple - they work well as musical collaborators as well. Jauregui has lent her talents to Ty's work before, and their joint track "In Your Phone" was featured on Ty's second studio album, Beach House 3
