Mercedes claims Bristol & Levi were ‘trying to conceive for months!’ Do you believe her?

Just when we thought we’d heard it all, Levi Johnston‘s sister Mercede goes and drops a HUGE bombshell about Bristol Palin! “Bristol’s pregnancy wasn’t … an accident,” she tells Playboy in a shocking new interview. “She and Levi planned it. They were trying to conceive for months.”

Mercede also says whenever Bristol drank it “made her more promiscuous,” adding validity to Bristol’s confession about being drunk on wine coolers when baby Tripp was conceived.

This whole thing sounds crazy to us, but then again, a lot of things about the Palin family sound crazy to us. What do YOU think, HollyMoms?
