Whitney Houston was reportedly 50 minutes late for her New York concert Sunday because she was stuck in traffic. But show up she did — belting out a mini-concert in Lincoln Center Plaza that signaled Houston’s first live public performance in the U.S. in 15 months, the New York Daily News reports.

“I love you, each and every one of you. I truly do,” the diva, 39,said as she took the stage blowing kisses to the adoring crowd.

The News reports that Houston (whose at times incoherent “Primetime” interview with ABC’s Diane Sawyer last week was called a “train wreck” by some critics) appeared healthy looking for her latest performance — far healthier than the skeletal frame she showed off during last year’s Michael Jackson tribute concert at Madison Square Garden.

On “Primetime,” Houston admitted to having been hooked on drugs, but that daily prayer now gives her the power to deal with life. She also said that she used to be addicted to making love.

Houston on Sunday performed “flawlessly” and to “deafening applause,” according to the Daily News, delivering two songs — “One of Those Days” and “Tell Me No” — from her new album, “Just Whitney.”

The mini-concert is due to air Tuesday on ABC’s “Good Morning America.”

Her only miscue reportedly came during a gospel rendition of “Do You Hear What I Hear?,” when the 35-member choir from Talent Unlimited High School joined in.

“Stop! Stop! We’re going to start this again,” Houston shouted a few verses into the song. Which she did.
