It seems Nathan Sykes is obsessed with his girlfriend Ariana Grande. After spending a week with her in London, Sykes can't wait to see her again.

"The Wanted" singer has joined Ariana in LA (Ariana had flown to LA to perform at "Jimmy Kimmel Live" show). Expressing his excitement on reuniting with his girlfriend, Nathan tweeted yesterday, "Landed in LA!!! Enthralled to be here!!"

Nathan is in LA to promote his new single "Show me the Love" and the upcoming album "Word of The Mouth".

Despite of Jai Brooks cheating allegations, Ariana and Nathan Sykes are going strong. Last week, the couple was spotted together on slew of dates in London. They were seen heading out for a dinner date to Sushi Bar and then to Bruno Mars' and Lawsons' musical concerts.

We wonder where the two will go in LA? To make things easier for Nathan and Ariana, we have chosen 3 romantic spots for them.

First up is Crystal Cove:

Crsytal Cove is the most beautiful beach in Southern California. What really make it special are its untouched beauty and azure waters. Ariana being a die-hard romantic would love to go on a beach date with her beau Nathan Sykes. And what could be more romantic then taking a quiet and exclusive walk down the beach, while the sun sets down.

Second on our list of most romantic places is The LA Last Book Store:

Ariana and Nathan both have an undying passion for music. The Last Book store in LA has some great musical record collection. They can spend a nice balmy afternoon sharing their thoughts on music while listening to some.

Third is Amusement Park:

If Nathan Sykes wants to surprise his lady love, then there is nothing better than booking an exclusive night at an amusement park. There are loads of amusement parks in LA such as "Knott's Berry Farm", "Disney", "Universal Studios", and "Six Flags". Nathan and Ariana can go on fun rides together under the enchanting light of stars.
