Actress Liv Tyler

Liv Tyler is an actress who can claim two links to rock royalty.

Born in 1977 to model Bebe Buell, then the live-in girlfriend of rock star Todd Rundgren, she found out later that Aerosmith frontman Steven Tyler was in fact her biological father, a role Rundgren, her adoptive father, assumed for the sake of appearances.  Liv legally changed her surname from Rundgren to Tyler as a result.  Ironically, Tyler was no more her father's original surname than her own; his original surname is Tallarico.      

Anyway, Liv Tyler could have been a singer like her two dads, but she became an actress instead.  She first gained notoriety in 1996's That Thing You Do!, a Tom Hanks-directed movie about a fictional rock band from Pennsylvania in 1964 aiming for stardom. Liv played the girlfriend of one of the band's members. 

Later roles included a part in Robert Altman's 2000 movie  Dr. T & the Women, as one of the girlfriends of the title character (played by Richard Gere) and her role as a therapist in 2007's Reign Over Me, a comedy-drama about the aftermath of 9/11.  Her best known roles are as Grace Stamper in Armageddon, a 1998 disaster movie about a giant meteor about to hit earth, and as Arwen Undómiel in three Lord of the Rings movies.

More recently, Liv Tyler has done smaller films, such as 2017's horror-fantasy film The Wildling.

Fun fact: "Liv" is not short for Olivia; Ms. Tyler was named for Norwegian actress Liv Ullmann  (an earlier honoree on this blog).
