Chet Hanks has become a father for the first time.

The 26-year-old musician - who is also known as Chet Haze - has credited his unnamed little girl for helping him turn his life around and get sober, after previously battling substance abuse issues.

Chet, who is the son of Tom Hanks and Rita Wilson, didn't reveal any details about his daughter, including her mother or when she was born, but admitted she is the ''best thing'' to ever happen to him.

In an emotional Instagram video, he said: ''I know I've been not that active on the 'Gram lately because I've been figuring out my life, which is what we're all doing, and social media's all bulls**t anyway. .

''With that being said, I want to share something today because it's about to be shared anyway in the press, which is the fact that I have a daughter.

''I do have a daughter. She's the best thing that's ever happened to me.

''She's the reason why I turned my life around and got sober. I've been sober for over a year and a half from everything.''

Chet has vowed to keep the youngster out of the public eye because he doesn't want her to be ''dragged into the negativity'' of his past.

He captioned the video: ''No disrespect to people that post their kids, I just I never wanted her to be dragged into the negativity surrounding my past.''

He also said in the clip: ''I don't share on her on Instagram. I don't post her on Instagram because her privacy is sacred to me. She is sacred to me. She is not something to be posted. She's something that I love, that's changed my life, but the fact is she's about to be shared with everybody so I wanted you to hear it from me...because I'm a real person.''
