It's never easy when the current girlfriend meets the ex girlfriend. It's even harder when the only thing they have in common - the boy - isn't there to help handle the situation.
So - it must have been awkward when Prince Harry's current love interest Cressida Bonas and his ex Chelsy Davy attended the same carol service in London on Wednesday.
The Christmas event was held in memory of Harry's close friend Henry van Straubenzee at St. Luke's church in Chelsea. Although he couldn't make it due to his charity trek in the South Pole, the two significant girls in his life were there to show their support.
Cressida kept her head down as she left the church in flared jeans and a suede coat while Chelsy appeared to be in high spirits.
After they split in 2010, perhaps Chelsy is well and truly over her ex boyfriend? Still, there must have been a few awkward glances in the middle of 'O Come All Ye Faithful'...
