'Bachelorette' couple Tayshia Adams, Zac Clark call off their engagement

"The Bachelorette" star Tayshia Adams and Zac Clark, whose engagement concluded season 16 in December, have broken up.

A representative for Adams, a former phlebotomist who has since gone on to co-host that ABC dating competition, told People magazine on Monday, "Tayshia Adams and Zac Clark are no longer a couple."

Neither Adams, 31, nor Clark, 37, co-founder of the Manhattan and Westchester County-based rehab facility Release Recovery, have commented publicly on the breakup.

Earlier this month, the couple ran the TCS New York City Marathon together.
