A mother is always the last to know.
While the rest of the world seemed to know about Bristol Palin hooking up with Levi Johnston, again, the couple went to great lengths to keep their relationship a secret from Bristol's mom, former vice presidential candidate, Sarah Palin.
Levi and Bristol have been living together in Anchorage, Alaska, for some time, according to neighbors who spoke to RadarOnline.com.
Said one: “Even though Levi spends the night at Bristol’s every single night, they have to be on high alert in case Sarah stops by to see Tripp.
“As soon as they hear her car, Levi escapes out the back door and waits for a text from Bristol to tell him the coast is clear!”
Despite making attempts to make amends with his soon-to-be mom-in-law, Levi clearly still has some work to do to win back Sarah’s support.
"Last year, after Bristol and I broke up, I was unhappy and a little angry,” Levi said earlier this month.
“Unfortunately, against my better judgment, I publicly said things about the Palins that were not completely true.
"I have already privately apologized to Todd and Sarah. Since my statements were public, I owe it to the Palins to publicly apologize."
Bristol and Levi announced Wednesday they were engaged, again, after twelve months of custody fights, child support battles — and a nude Playgirl spread.
