FemaleFirst reported that the couple have been dating since the month of August and would like to do a tribute to their idols of the group Oasis by doing a duet.
A source revealed, "Rhys really likes Oasis, particularly Noel Gallagher so that’s the kind of music he would like to make."
Miller has always dreamed of becoming a singer and thinks that a song with Ifans will be a hit. Ifans is a friend of the band members of Oasis, Noel and Liam Gallagher. He even makes an appearance in one of their videos, The Importance of Being Idle.
