Posh Spice is back!

Victoria Beckham showed up on Wednesday's Late Late Show With James Corden but it was her Instagram story that really got her fans excited. The former Spice Girls singer posted video of herself in the car with Corden, announcing that they were shooting Carpool Karaoke.

While many fans were thrilled at the possibility of seeing Beckham perform again, one Twitter user was displeased that she would agree to Carpool Karaoke but not a Spice Girls reunion. "So Victoria Beckham can do a Carpool Karaoke with James Corden but not do another Spice Girls reunion? Am I right?" read the comment.

Beckham recently shot down any hope of a Spice Girls reunion when she was on the Today show. "There won't be a reunion because I think that when we performed at the Olympics, it was so great. And that was us, celebrating everything that we had achieved," she said. "But I still talk to the other girls. We're still very close. But I think you need to -- you need to know when it's time to actually say, 'That was great, we achieved a lot.' And everybody moves on."

Beckham, 42, had lots of fun in the Late Late Show studio on Wednesday. The mother of four participated in a game of Flinch with Corden, Lisa Kudrow and Jessica Chastain, but wasn't so good at not flinching when fruit was thrown at her face. "Did I flinch? I didn't flinch?!" she quipped on Instagram. "Who knew fruit could be so scary?!?"
