Justin Bieber whisked his girlfriend away for her 18th birthday

The Biebs and his new model girlfriend, Sofia Richie, have jetted off to celebrate her 18th birthday. 

The couple were seen boarding a private jet (naturally) on Wednesday, donning matching grey and white track-suits. 

Sofia, who is the daughter of music legend Lionel Richie, documented the "gettaway" on Snapchat. 

The 18-year-old socialite posted a picture of candles in the shape of a heart when she arrived at her exotic destination with her new fella. 

Cute right? 

The pair have been officially dating for just a few weeks now, but things certainly seem serious. 

Ah, to be young and in love (and a millionaire)!
