Theeeeeyyyy're baaaack! Newly-engaged couple Justin Bieber and Hailey Baldwin are back in LA following their whirlwind engagement in the Bahamas and then a quick trip to Miami and fans are going WILD with the news that these two will soon be married.

We asked Hailey, during her daytime workout, if pal Kendall Jenner would be her maid of honor and reports say Post Malone wants to be Justin's best man and to perform at the nuptials!

The pair rolled up to their hotel in Justin's sick Lambo Saturday night. We can only imagine how INSANE the paparazzi and fan attention on these two will be, now that they're the world's #1 supercouple. Long live Jailey!
