Chief Keef is all about knocking the ladies up.

This week, he managed to get a coed he'd never met before pregnant.

Welll, sort of. Here's the Sosa-sized prank Zach Svobodny pulled on his sister Morgan.

OMG MY BROTHER IS SUCH AN ASS. HE PHOTOSHOPPED A PIC OF ME WITH CHIEF KEEF & SENT OUT THESE CHRISTMAS CARDS pic.twitter.com/Aac4SF8qY8

The Christmas card reads:

Happy holidays, everyone! I hope you all had an amazing 2016 and are looking forward to making 2017 even better. This year has treated me fantastic! Since September, I’ve been in a very serious relationship with an amazing guy named Keith Cozart, a famous rapper who some of you may know as Chief Keef. He has many hit songs that you’ve probably heard, such as “That’s The Shit I Don’t Like,” “I Hate Being Sober,” and “These Bitches Love Sosa.” Keith is an amazing guy with a lot going for him and this is the happiest I’ve been in at least 6 months! I dropped out of college last month because I found out that I’m pregnant and I’m pretty sure Keith is the dad (not positive though). Keith and I plan on moving to Atlanta in March and we couldn’t be more excited!! Best wishes to you all in 2017!! P.S. Bang Bang

Zach, who's good with the Photoshop, says Morgan's not even pissed about the prank since it went viral.

“My sister won't retaliate. She's happy for the 15 minutes of fame. As Twista would say, I made her a celebrity overnight,” he told Complex. “[…] I'm still surprised Chief Keef hasn't responded to it yet cuz [sic] I know damn well that he's seen it.”
