In a word: Beyoncé .
The superstar singer, who headlined the 2013 Super Bowl halftime show, will share the stage with Coldplay when the four-man band performs at Super Bowl 50 on Feb. 7 at Levi's Stadium in Santa Clara.
By coincidence, Beyoncé is the guest singer on "Hymn for the Weekend," a song from Coldplay's seventh and newest album, "A Head Full of Dreams."
The question now, at least for fans of Queen Bey, is: How much will she steal the show from Coldplay? (The same question could be inverted to ask: How hard will it be for her to tone down her act in order not to steal the show from Coldplay?)
Actually, there are other questions to ponder as well. Namely, are Chris Martin and the other members of Coldplay at this very moment learning how to play "Drunk in Love" and "Single ladies (Put a Ring On It)?"
Can Martin rap? Or will he move back to the piano and invite Beyoncé's husband, Jay Z, to drop some rhymes?
In turn, is Beyoncé learning such Coldplay songs as "Clocks" and "Vida La Vida?" Will Martin and Beyoncé do any joint choreography? Or will he wisely let her command center stage? And will either of the two dancing sharks who accompanied Katy Perry at last year's Super Bowl halftime show make a cameo?
Either way, Beyoncé's addition to the lineup seems like a well-calculated move by the NFL and Pepsi, the halftime show's corporate sponsor, to boost ratings.
