We never saw this duo happening.

Andy Murray has been criticised by some over the years for his 'lack of personality' and regular gets flack for his muted demeanour. Not usually a fella to be seen having the craic or messing about, poor Andy has as a result been dubbed 'boring' by many. Well, it was sink or swim for the sports star when he was asked to complete a series of questions to raise money for Sport Relief. Doesn’t sound too difficult, does it? Well, add in Michael McIntyre waking him in the middle of the night to answer those questions and Geri Halliwell coming along for a spot of karaoke and it suddenly becomes quite the piece of telly. In the final round of his quiz, Andy was asked to complete the lyrics of some Spice Girls tracks and while it may have been a little awkward, the tennis champ absolutely smashed it. He's clearly a HUGE Spice Girls fan.

No @andy_murray, this is not a dream. @GeriHalliwell really IS in your bedroom making you sing Spice Girls songs ?@sportrelief #SportRelief pic.twitter.com/DS2xoRSa4O

The moment was one of the most bizarre things we’ve ever seen on telly and we weren’t the only ones who thought so.

So @andy_murray singing Spice Girls is probably one of the best TV moments ever #SportRelief2018 #SportRelief
