If you've ever thought kids grow up too fast, you're not alone. tobyMac is probably with you! His son, Tru, also known as truDog, appears in multiple tobyMac albums in songs like "Hype Man (truDog '07)." Well, no truDog is all grown up and working on his own gig. He's featured on a brand new single by Hollyn called "Alone" and his rapping is pretty impressive.
