She may be back in Los Angeles now, but we can't stop staring at Kim Kardashian's sexy pictures from her romantic Mexican vacation with hubby Kanye west!

Shortly before jetting home yesterday, Kim posted the snapshot above and captioned it, "Last day to get my tan in..." and she also added the pic on the right and wrote, "Heaven on Earth! Thank you @realjoefrancis for letting us stay at Casa Aramara!" Sorry, but all we're looking at here is those boobs!

The other day Kim shared a picture of herself smooching daughter North West after the 13-month-old celebritot took her first steps, and she wrote, "Our baby girl finished one week of swimming lessons today then took her 1st steps right when she got out of the pool!!!! Mommy & Daddy are so proud of you!!!!" Sounds like the family was having a blast down there!

Kimye honeymooned at Joe's mansion in June, and a source tells Us Weekly that the duo are so eager to have a second child, that they went back to the romantic spot with the sole intention of it being a baby making trip. Guess we'll find out soon enough whether or not Kim has a bun in the oven!
