ATLANTA, USA (AP) — Rapper Wiz Khalifa says preparation for becoming a first-time father and husband has helped put him in a more mature musical state of mind.

But that doesn’t mean Khalifa will refrain from his weed-smoking, rock star-like ways.

“I’m at a different point in my life,” said Wiz Khalifa, whose sophomore album, O.N.I.F.C., debuted at No 2 on Billboard’s 200 albums chart this week with 141,000 copies sold, according to Nielsen Scan.

“I just want to say things a little bit differently and express myself on another level on the album,” he continued. “I have new responsibilities, but I’m always going to smoke weed and enjoy myself. My son is going to love me for the same reasons others do. I’m not just going to turn into some old fart.”

For the 25-year-old Wiz Khalifa, life is just getting started. He and his fiancée, Amber Rose, who is in her third trimester, are expected to get married at a courthouse in a few weeks.

Wiz Khalifa said he and Rose — an ex-girlfriend of Kanye West — want to marry before the birth of their son. He said they will hold a traditional wedding ceremony later with family and friends.

“There’s a lot of excitement going on,” the Pittsburg-based rapper said. “I just worked my (butt) off and tried to be better every day. I’ve just tried to move forward naturally.”

Rose, a model and rapper, appears on Wiz Khalifa’s new album. It also features Pharrell, 2 Chainz and the Weeknd, who appears on the current single Remember You. The first single, Work Hard, Play Hard, is a platinum Top 20 hit.

While the album is finally out, Wiz Khalifa and his record label, Atlantic Records, initially struggled over the creative process for O.N.I.F.C., which stands for Only N-word in First Class.

He said his label wanted him to focus on producing big hits, similar to his omnipresent jam Black and Yellow, which skyrocketed to the top of charts and helped previous album, Rolling Papers, sell nearly 200,000 copies in the first week last year and eventually reach gold status.

Wiz Khalifa felt otherwise, saying there was a lack of communication between himself and label executives.

“I had less freedom to be creative, but it’s all about communication,” he said.
