Real Housewives of New York City
lovebirds Alex McCord
and Simon van Kempen
toasted their 10th anniversary with a romantic dinner for two at Georgica in Wainscott, N.Y., recently. The pair dined on veal Milanese and truffle lobster mac 'n cheese before tucking into a selection of desserts – topped with a tourmaline-and-diamond gold ring van Kempen gifted his wife. "She was shocked but seemed so happy," a source tells PEOPLE. "It was like no one else was in the room." The two – who got "a little tipsy" on red wine – stayed until 3 a.m., dancing the night away.
