Aerosmith frontman Steven Tyler took a page from J.R.R. Tolkien in his birthday message to his daughter Liv Tyler on Twitter Friday.

The rockstar dad referenced Liv Tyler’s turn as the half-elven queen Arwen in Peter Jackson’s big-screen adaptations of Tolkein’s The Lord of the Rings series. “HAPPY BIRTHDAY @LIVTYLER…MY MAGICAL HALF-ELVEN EVENSTAR,” the former American Idol judge wrote. “I LOVE YOU TO THE END OF THE GALAXY AND BACK.”

Liv Tyler, who turned 39, is headed into filming the third season of her HBO drama Leftovers. And Steven Tyler’s new album “We’re All Somebody from Somewhere” releases on July 15.
