The Gates are open … to marriage.

Bill and Melinda Gates’ daughter Jennifer is engaged to Egyptian showjumper Nayel Nassar.

The med student posted a photo of herself canoodling with the equestrian in the snow, saying Nassar “absolutely swept me off my feet this past weekend … I can’t wait to spend the rest of our lives learning, growing, laughing and loving together.”

Just a week ago, Gates posted a birthday tribute to Nassar: “Can’t begin to put into words how extraordinary you are … The most compassionate, intelligent, hilarious, supportive, warm, humble human being.”
