The Danish defender turned 22 this week and relaxed with his girlfriend on Tuesday night as the couple enjoyed a meal out together.
Christensen has been earning plenty of praise for his mature performances for Chelsea FC this season since breaking into the first team after a two-year loan spell at Borussia Monchengladbach.
The centre-half has made 24 Premier League appearances this season and has been rewarded with a new and improved long-term Chelsea FC contract at earlier this year.
And the defender looked to be pleased to be spending some time with his partner on Tuesday night as he celebrated his 22nd birthday.
His girlfriend Katrine posted the picture above of the happy couple on her personal Instagram story.
Christensen will be hoping to help Chelsea FC return to winning ways in the Premier League on Saturday lunchtime when they take on Southampton at St Mary’s.
The Blues are currently in fifth place in the Premier League table and 10 points behind fourth-placed Tottenham with just six games left after their disappointing 1-1 draw with West Ham United last weekend.
