Boy, how fast they grow up. It seems like it was just yesterday when Diggy Simmons was just a little tyke running around on his dad's MTV reality show 'Run's House.'

But now at 19, the rapper, TV personality and fashion-head is all grown up and singing about missing his girl on the road. The cut is called 'Honestly,' and Diggy gets pretty sentimental pretty fast.

"You gave me a picture of you and I framed it / And all of my n----- be playing and claiming / You need to feel this it's straight out the chest / I be on tour buses dealing with mess... And honestly the road can get cold / Sometimes I need something I can hold," he croons.

It sounds like Simmons has been listening to a lot of Drake since he released his debut album, 'Unexpected Arrival.'

There's no word yet on when Simmons' sophomore LP will arrive. But one thing's for sure: you can clearly hear he's matured on this new track. Gone are the squeaky pre-pubescent vocals that he used on songs like 'Copy, Paste' and 'Do It Like You' back in 2011. He's on his grown man tip here.

Hopefully he'll start carving out his own sound and leave the Drake-styled vocals alone.
