Looks like Donald Trump Jr. might be closer to his dad's ex-wife than he is to the first lady. President Donald Trump's eldest son was all smiles as he posed alongside Marla Maples at his fiancée Bettina Anderson's bridal shower on April 12, fueling rumors of awkward tension between him and stepmom Melania Trump - who was a no-show at the special occasion, Wonderwall.com can reveal. Maples and the president share daughter Tiffany Trump, who was also featured in the photo next to the bride-to-be. Don Jr.'s other sister, Ivanka Trump, also made an appearance at her future sister-in-law's party.
