'' Speaking to PEOPLE at the Sundance Film Festival , where she 's promoting her new movie `` Robot and Frank , '' the actress , 34 , also revealed that she 's finally following in her father 's footsteps -- into the music business . `` I got to record a cover of INXS 's ' I Need You Tonight ' for a Givenchy commercial , '' says the model , who has a longstanding beauty contract with the European cosmetics company . `` It was fun and terrifying and wonderful , '' she says of recording the song , which is due out soon . It 's a logical step for a woman whose roots are in music . `` I always thought when I was a little girl that I 'd be a singer , '' she says . `` My mom [ Bebe Buell ] was always in bands . My dad . And my stepfather , Todd Rundgren , is an incredible musician . '' As for her dad 's dicey performance of The Star-Spangled Banner on Sunday ? Liv had n't seen it yet . `` Somebody told me my dad just sang the national anthem , '' she said . `` I 've got to go Google it . '' Or , you know , maybe not .
