A pajama-clad Mariah Carey, wearing shades and sipping a drink, was spotted yesterday strolling in the lush garden of her mom's suburban home, where the singer is recovering from a nervous breakdown.

In the first photograph since the 31-year-old diva was released from Connecticut's tony Silver Hill Hospital on Tuesday, Carey sported a jaunty ponytail and appeared cool and calm despite the oppressive heat. 

Wearing pajamas with sky-blue and white clouds on them, Carey walked for just a few moments on the leafy property of the Goldens Bridge, N.Y., home, sipping a yellow-colored drink through a pink straw. Two dogs frolicked as she walked. 

The garden on Patricia Carey's property has a pond and is sprinkled throughout with Adirondack chairs. 

Two livery cars came in and out all day, dropping off passengers and supplies. Security was kept tight. 

In a statement yesterday, Carey's spokeswoman, Cindi Berger, said the singer was "feeling better." 

"She is resting under a doctor's care . . . with her mother." 

Meanwhile, more chilling details have emerged about the frantic 911 call Patricia Carey placed to police the night of her daughter's nervous breakdown July 25. 

The singer could be heard shrieking as she smashed glassware and plates — and then stomped on them, cutting her hands and feet  in the background on the 911 phone call, a source said. 

The elder Carey told the 911 operator she couldn't get her daughter to go to the hospital "on her own," said the source who reviewed the tape. 

"She was a mother who could not control her," the source said. 

"The mother asked for help — 'You have to come help my daughter,'" the source said. 

When a state trooper arrived, "She was pretty cut up," the source said of the singer. 

"You could hear her smashing glass on the tape. Her hands and feet were cut. She was apparently stomping on the glass," the source said. 

But the trooper later wrote up in his report of the incident that he transported Carey and her mom to a northern Westchester County hospital without incident — and that he never had to place her into custody by invoking the Mental Health Law, the source said. 

Representatives of the singer have strongly denied the incident was a suicide bid. 

Carey canceled all public appearances after her breakdown, including her headline role at the Aug. 1 show celebrating the 20th anniversary of MTV. 

In recent months, Carey filmed two movies, Glitter and Wise Girls. She also wrote, recorded and produced her newest album, the soundtrack to Glitter, which is due for release on Aug. 21.
