Singer Cody Simpson's girlfriend Gigi Hadid wants him to surprise her in New York City for Valentine's Day Feb 14 because she is working "the entire day".

The Sports Illustrated model admits she probably won't be able to celebrate the occasion with a romantic holiday with the 18-year-old Australian singer, but she hopes he can fly to her.

"I'm working the entire day but hopefully my boyfriend can fly in," Hadid told eonline.com.

Asked about her favourite way to spend a date with the heartthrob, she said: "We go to McDonalds and have dates and it's awesome. But I think for Valentine's Day, maybe just a place with lights hanging."

The couple rekindled their relationship in November 2014. They had parted ways last summer due to their hectic careers.
