Sandra Bullock has fuelled speculation that pop star Olivia Rodrigo and Fleetwood Mac's Stevie Nicks will feature musically in "Practical Magic 2," posting an Instagram Story video of the pair performing together with the caption "Angel voices that are part of an upcoming film…." Representatives for Nicks, Rodrigo and Warner Bros had not responded to requests for comment, but the hint carries weight given Nicks contributed two songs to the original 1998 film, both produced by Sheryl Crow.

The tease followed Rodrigo bringing Nicks on stage at Saturday's Daisy Chain Fields festival to perform Fleetwood Mac's 1975 classic "Landslide," with Nicks praising the younger singer's stage presence. "Practical Magic 2" reunites Bullock with Nicole Kidman, is directed by Susanne Bier and opens in cinemas on 11 September, with a supporting cast including Stockard Channing, Dianne Wiest, Joey King, Maisie Williams and Lee Pace. The sequel arrives amid a broader wave of Y2K-era nostalgia revivals in Hollywood, following films such as "The Devil Wears Prada 2" and "Toy Story 5."
