WATCH: Love is in the air in Doha, and New York

Valentine's Day came in the midst of a busy week of tennis. Over in New York, one fan made his love for Bob and Mike Bryan known to the world very vocally from the stands.

Unfortunately, the passionate support couldn't put the Bryans into the second round as they fell to Tennys Sandgren and Jackson Withrow, 7-6 (9), 6-4.

Over in Doha, players competing in the WTA Premier event had a message for their fans, and for their significant others.

In the Doha semifinals on Friday, Elise Mertens takes on Angelique Kerber while Elina Svitolina will face off with top seed Simona Halep.
