Kobe Bryant, Olympic swimmer Michael Phelps, skateboard king Tony Hawk and Madonna's reported lover Alex Rodriguez have formed a supergroup for a new TV ad.
The superstar sports quartet will perform Bob Seger's Old Time Rock + Roll for an upcoming Guitar Hero promo.
Basketball star Bryant will act out Tom Cruise's moves from the film Risky Business, while Phelps, Rodriguez and Hawk provide back-up.
Cruise lip-synced to the song in the cult 1980s movie.
