Taylor Swift's concert is a family affair ... 'cause apparently her opener Suki Waterhouse's baby daddy Robert Pattinson's in the crowd -- and Paramore made a Twilight reference to highlight him! The rock band took the stage at Wembley Stadium in London not long ago ... and, before their song "Decode" they shouted out the actor, dedicating the track to him. Hayley Williams dedicated Decode to Robert Pattinson at #LondonTSTheErasTour tonight! “[…] I’d like to dedicate this next song to Mr. Waterhouse. He has the skin of a killer, Bella. It's for you, Robert.” pic.twitter.com/vHWnCqmaJ0 Check out the video ... Hayley Williams calls him "Mr. Waterhouse" -- a cheeky nickname for the star -- before adding he has a killer's skin, a oft-quoted line from "Twilight." While they didn't show RP on the big screen, we know why he's there ... to support Waterhouse, who opened the show -- driving 90k fans wild at England's largest venue. suki waterhouse performing “good looking” today at the eras tour in wembley! #LondonTSTheErasTour@sukiwaterhouse i’m so incredibly proud of you!! you did it
