AceShowbiz - Hailey Baldwin is a huge fan of Justin Bieber's new song "No Brainer", which sees the Canadian singer reuniting with DJ Khaled, Quavo and Chance the Rapper. It's reported that the new summer anthem successfully "turns on" the 21-year-old model with its lyrics.

"Hailey melted when Justin told her she helped inspire some of his vocals in his new song," says a source to HollywoodLife.com. "Justin always reminds her that she is drop dead gorgeous and that she moves his soul, so hearing him sing the words in the song means a lot to her. Being a part of Justin's music makes Hailey feel special and she has been listening to his new song non-stop."

"Hailey loves Justin's new song. She thinks he is so amazingly talented and watching him work in the studio is a total turn-on," the source continues. "She felt so lucky to be with Justin when he laid down some of the vocals for his new song with DJ Khaled and she thinks it is awesome to have been able to watch it come together now that it is out for the world to enjoy too."

The newly-engaged couple, who was spotted making out at 12 Chairs Cafe in Brooklyn on July 16, was caught having another happy couple time in New York City while grocery shopping on the same day. The two, looking loved up as always, hit the streets of Brooklyn before stopping by City Acres Market in the Williamsburg portion of the borough.

"Justin and Hailey didn't leave each other's side while purchasing several items," an onlooker told HollywoodLife.com. "They looked comfortable and sweet together even as they did simple grocery shopping. She was smiling and seemed proud to be with Justin."

"They looked like a regular, normal, happy couple in love as they held hands the entire time," the eyewitness went on saying. "Justin was clearly protective of Hailey as he led the way during their shopping trip. Hailey looked gorgeous and showed off her toned abs in a cropped top and hot pink jogger pants."
