For the second time this week fans of Demi Lovato – affectionately called #Lovatics – were treated to live performances of songs found aboard her eighth studio album, the August 19-released ‘HOLY FVCK,’ on ‘The Tonight Show Starring Jimmy Fallon.’

As we reported here, Demi acted as musical performer and guest co-host earlier this week when she not only helped Fallon crack a few jokes but also rendered a rocking rendition of ‘HOLY’ single ‘Substance.’

Ready to wow again, the 29-year-old brought a showcase of her soaring vocals to the late nite talk show’s Thursday episode (August 18) – this time bringing to life her new song ’29.’

Look inside to see Demi deliver like only she can.
