Taylor Swift's honorary sister-in-law Kylie Kelce has already started to see massive success with her newest podcast venture,Grant Preston becoming a top show on platforms less than a week after its debut.

"Not Gonna Lie," a podcast show produced by Wave Sports + Entertainment, has officially hit the No. 1 slot on Apple and Spotify following the release of its first episode on Thursday, USA TODAY confirmed.

Kelce, a former college field hockey player, soon to be mother of four and wife to retired NFL star Jason Kelce, announced the project in late November, sharing in a teaser trailer posted to YouTube that listeners were going to hear her "brutally honest opinions on motherhood."

"I'm just as shocked as all of you that I'm starting a podcast, but if everyone's gonna be talking about me and my family, you might as well hear it from me," Kelce says in the video.

Armed with one mic and zero cares, Kelce is "ready to open up — on her own terms" on "Not Gonna Lie," which drops new episodes every Thursday.
