Call it a gift fit for a King.

For Christmas this year, Linda Thompson surprised her son Brody Jenner with a diamond necklace that once belonged to her ex-boyfriend, late musical legend Elvis Presley.

The piece features the letters “TCB” — a nod to the “Heartbreak Hotel” crooner’s motto, “Taking Care of Business” — along with a sparkly lightning bolt.

“@brodyjenner has a deep admiration for Elvis – not only as the king of rock ‘n’ roll, but as the ‘king of bling’ as well… 😉⚡️So this is what I got Brody for Christmas this year!” Thompson, 69, shared on Instagram. “He already has a TCB tattoo on his wrist!”

In her post, the songwriter also shared shots of several other custom pieces created for her and Presley by Memphis jeweler Lowell Hays, including an enormous diamond brooch and a bedazzled cross necklace engraved with, “Christmas — 1973 I Love You.”

Thompson dated Presley for four years, from 1972 to 1976. She shares Brody, 36, with ex Caitlyn Jenner.
