Post Malone has announced that he and his girlfriend are expecting their first child together.

The 26-year-old rapper has kept his romantic life out of the spotlight since finding fame, so not much is known about his mystery partner.

But despite wanting to keep his family's life private, he couldn't help but share the exciting news that he'd soon be becoming a father

Post Malone - real name Austin Richard Post - shared the announcement with TMZ, telling the outlet: "I’m excited for this next chapter in my life," before adding: "I’m the happiest I’ve ever been, and for since I could remember I was sad."

The rapper also announced that, with the news of a baby on the way, he has decided to start taking better care of himself.

"Time to take care of my body and my family and friends, and spread as much love as we can every day," he said.

According to sources close to the couple, Post and his girlfriend celebrated their happy news with a quiet private party in Southern California over the weekend. Close friends and family were invited to toast the exciting news that the two would soon be parents.

And as if having a baby on the way wasn't enough, Post Malone has also recently revealed that he's got a new album on the way.

Twelve Carat Toothache will be the artist's fourth studio album and is expected to drop next month on June 3.

In an interview with Billboard earlier this year, Post said the new album would: "speak more to how I’m feeling at the moment: the ups and downs and the disarray and the bipolar aspect of being an artist in the mainstream."

He went on to explain that the new album will be slimmer than his previous outputs, at just 45 minutes long. The idea behind this was to avoid filler tracks and only release the music he really wants to.

"I’ve made a lot of compromises, especially musically, but now I don’t feel like I want to anymore. I don’t need a No. 1; that doesn’t matter to me no more, and at a point, it did," he explained.
