The father of three, 32, has apparently decided to do it to take revenge on Bieber after the "Sorry" singer hooked up with his partner Kourtney Kardashian, reported Ace Showbiz.
"Scott's rolling out the red carpet to get Selena's attention and he did so in the most grandiose way," a source said.
"He's very resourceful and got her contact information and sent her beautiful gold-plated poinsettias and they were arranged in the shape of a Christmas tree."
Scott invited the "Hands to Myself" singer to join him in Las Vegas for the New Year's Eve.
