Prince Harry has reportedly fallen hard for British pop star Mollie King. The two recently performed a late night karaoke session at London's Bunga Bunga club last weekend. According to a source, "it's very early days for them but they're head over heels. Last weekend, Bunga Bunga closed at 3am, only open to special guests, including Harry and Mollie. The two reportedly guzzled down cocktails before leaving separately to avoid attention. The 24 year-old singer is best known for being a part of the girl group The Saturdays.
