Known worldwide as River Song, the mysterious wife of the Doctor, Kingston’s casting has sent shockwaves through the fandom and sparked wild speculation about whether her routines will nod to the sci-fi classic.
But beyond the glitz of the ballroom, Kingston’s life has been anything but ordinary. From Hollywood success to headline-grabbing heartbreak, her story is as dramatic as any prime-time soap.

Inside Alex Kingston’s Turbulent Love Life — Including Her Marriage to Voldemort Actor Ralph Fiennes
Away from the cameras, Kingston’s personal life has been just as gripping. She’s been married three times, with her first marriage to fellow actor Ralph Fiennes grabbing headlines worldwide.
The two met at the Royal Academy of Dramatic Art (RADA) and tied the knot in 1993 after a decade together.
