If you asked us what Gwen Stefani and Eminem had in common, we’d answer that they are both platinum blondes whose best songs came out in the mid- to late 90s.

Now we can say they released a song together, too. Their collaboration, “Kings Never Die,” appears on the “Southpaw” soundtrack.

The track follows Eminem’s “Phenomenal,” which also appears on the film’s soundtrack and was released in June.

The 42-year-old rapper was, at one point, set to star in the film, which now features a super jacked Jake Gyllenhaal. Gyllenhaal plays a professional boxer who struggles to put his life back together and regain custody of his daughter after the death of his wife, played by Amy Adams. Rachel McAdams, 50 Cent, Rita Ora and Forest Whitaker also star.

“Southpaw” hits theaters July 24.
