REALITY TV star Gia Allemand was laid to rest in a simple ceremony Thursday as dozens of weeping mourners crowded into the church where she was confirmed as a child.

The suicide victim’s mother, Donna Micheletti, was overcome by tears when she entered the chapel at Trinity Grace Church in Chelsea. The casket had arrived moments before in a white hearse preceded by a black flower car adorned with pink and yellow roses that spelled out “Gia.”

Allemand’s boyfriend, NBA player Ryan Anderson, was pale and subdued in a dark charcoal-gray suit with a yellow rose in his lapel as he entered the church behind Micheletti.

Eugene Allemand, the tragic beauty’s father, was stoic throughout the somber 40-minute service, sitting quietly through “Amazing Grace.”

He later said he’s “in the dark” about his daughter’s final resting place.

“It’s frustrating,” he said. “I wish I knew.”

Allemand shot to reality-star fame by appearing on the 14th season of “The Bachelor: On the Wings of Love.”

The Queens-born beauty was arguing with Anderson on Aug. 12 because she suspected he was cheating on her. As he dropped her off at her apartment, Allemand said she loved him, according to a New Orleans police report.

Anderson responded, “I don’t love you anymore."

She went to her apartment and wrapped a vacuum cleaner cord around her neck. Doctors declared her brain-dead and she was taken off life support two days later.
