"Bachelorette" alum Kiptyn Locke is a dad! The former contestant and his girlfriend Samm Murphy welcomed their first child, son Koltyn Murphy Locke, on Thursday, July 16.

The first-time father announced the arrival of his newborn on Instagram with a photo of himself cuddling with his son.

"I promise to be there for you, always. To put you first, support you, and be someone you can count on - no matter the situation, time or place - I'll be there for you," the 37-year-old captioned his photo. "I promise to live my life in a way that gives you an example of a good man and positive role model. I will teach you to respect, appreciate, and love a woman. To open doors, take your first bite second, and be a source of strength, security, and caring."

People reported in March that the Southern California businessman and his girlfriend were expecting a son in July.

In his lengthy caption, Locke vowed to share with his son "the importance of passion in all aspects of life: sport, relationships, work, your personal interests and beyond as you show up to each and every day. And when you find your passion I will support you, encourage you and stand behind you no matter where you find it. Your happiness will always be enough to make me happy. You will never be alone in this world."

He continued: "I promise to show you how looking out for those around you, whether best friends or strangers, makes our world a better place. I'll teach you to never underestimate the value of humor, never compromise your principles, and always remember the importance of family, friends, loyalty, integrity, and character. I promise to introduce you to many of this big world's greatest treasures and then encourage you as you forge your own path and become your own man."

Locke ended his post promising to love his son unconditionally "each and every day until I take my last breath. Welcome to the world, son. "

Locke was a runner-up on season five of ABC's the "Bachelorette" with Jillian Harris. He also appeared on ABC's "Bachelor Pad" where he dated fellow contestant Tenley Molzahn.
