Jaden Smith gets Kylie Jenner a gold necklace

Nov. 21 (UPI) -- Fifteen-year-old Jaden Smith gifted his 16-year-old girlfriend Kylie Jenner with a gold necklace while the two strolled around in West Hollywood at Crystalarium on Tuesday.

After helping Jenner put on the necklace at the upscale jewelry store, the couple stopped by for a "romantic lunch" at Urth Caffe on Melrose Ave where they sat outside to enjoy their meal.

The After Earth actor and the Keeping Up With The Kardashians star have been friends for years and they reportedly started dating in March.

"It's new, but they've been friends forever," a source told Us Weekly at the time.
