The couple, who have been dating for one year, couldn't hide their fondness for each other as they sat side by side at dinner.

The nine-time Grammy winner and close friend of the Obamas, who sang for Barack at the 2012 Democratic National Convention and reportedly attended Michelle's 50th birthday bash, had guests up and dancing after dinner.
