Gov. Andrew Cuomo and ex-wife Kerry Kennedy greeted each other with warm kisses Wednesday as they joined forces to hail a new law to aid farm workers.

Kennedy gave Cuomo a smooch on the cheek before her ex-husband signed into law the Farm Workers Bill – which provides workers with collective bargaining rights and a set 60-hour work week that she’s long advocated for.

Afterwards Cuomo kissed Kennedy on the temple.

“I believe Robert Kennedy would be most pleased to know the great courage and perseverance that he so admired was shown by the Robert F. Kennedy Memorial, led by his own daughter, Kerry, and by his granddaughters — Cara, Mariah and Michaela,” Cuomo said while looking fondly at his ex.

Mariah and Cara also attended the ceremony in downtown Manhattan.

The couple divorced in 2005 following a 15-year marriage.

“When I was HUD secretary, with Ethel and Kerry’s advocacy, we worked with the migrant farm workers on the Texas-Mexico border … and with their help we built new housing and we built new facilities. That was 30 years ago and Kerry Kennedy never gave up the fight. Congratulations,” Cuomo beamed.

“Kerry then enlisted our daughters, who went to Albany to protest and advocate for the bill’s passage every year,” he said.

Kerry and daughters Cara and Mariah surrounded the New York governor as he signed the bill.

Cuomo gave one of the signing pens to Kennedy, who stood closely on his left.
