Bruce Jenner's suspicious behavior has his stepdaughters raising questions on Sunday's season premiere of Keeping Up With The Kardashians.
But Bruce's secret in question isn't the Olympian's reported transition to womanhood, though that may be addressed later in the season.

Kourtney, Khloe, and Kim Kardashian become suspicious of their dad after Kourtney eavesdrops an odd phone call with a certain friend of the family.
Ch-ch-check out the clip (above)!!!
Later, Kim confronts hers stepdad about the call, and Bruce gets a bit defensive:
Although the woman's identity is never revealed, we suspect she is Ronda Kamihira, a close friend of Bruce's ex-wife, Kris Jenner!
We'll see if the relationship plays out in front of TV cameras, but paparazzi caught the couple looking very cozy back in November, when filming for Season 10 of KUTWK was taking place.
