The "Selling Sunset" star, 33, revealed the premarital tidbit alongside the "Flip or Flop" star during a joint appearance on the "Not Skinny But Not Fat" podcast, per People magazine. Amanda Hirsch, host of the show, asked the star whether she'd tack the name on to the end of her own, effectively making her Heather Rae Young El Moussa. "I’m going to be Heather Rae El Moussa," Young revealed. "I’m going to drop my last name." El Moussa, 39, said that there may be an additional change in the works as well.
