On to the next one! Jay Z is ringing in his 45th birthday in Iceland with his wife Beyonce. The rapper, who tuned the big 4-5 on Thursday, Dec. 4, jetted off to the Nordic country on Monday with Queen Bey in tow for some well-deserved birthday R&R.

According to reports, Blue Ivy's (who has yet to be sighted) parents are staying at the luxurious Trophy Lodge in Úthlíð, South Iceland. 

So far on the couple's agenda? Visiting the breathtaking Blue Lagoon Geothermal Spa, one of the most visited attractions in Iceland. The power couple, who were snapped decked out in cold weather wear, took a helicopter to the spa on Jay's birthday, which is located in a lava field in Grindavík on the Reykjanes Peninsula.

 

According to the spa's website, visitors get a complete spa experience and can enjoy a silica mud mask while floating in the mineral water. 

Jay Z and Bey are also reportedly going to take a helicopter over the Holuhraun eruption, a volcano that has been active since this past August.

 

In September, Jay celebrated his wife's 33rd birthday with an equally satisfying yacht trip and a 33-second tribute video dedicated to the "Drunk In Love" singer posted on his YouTube page. 2014 was a big year for the couple, who embarked on their world-wide On The Run tour and were rumored to be on the brinks of divorce.
