The affectionate duo was spotted at the Cold Process Coffee and Tea pop-up stand at New York's Pier 57 last Sunday around 3 p.m. As they ordered refreshments, the couple couldn't resist sneaking in a few sweet smacks on the lips.
An onlooker told PEOPLE that Gyllenhaal, 32, who was a presenter
two weeks ago at the Tony Awards ceremony in New York, and brunette Miller, 23 , who made her SI
debut in 2011, appeared to be more than just friends as they were sweetly affectionate with each other.
"You could tell they were a couple. There was lots of PDA going on," the eyewitness said of their bike date. "They didn't make out, but they would kiss each other on the lips multiple times. More like little pecks and they were very touchy-feely. They couldn't keep their hands off of each other."
The two were with some friends and hung out talking for about 20 minutes at a picnic table. They seemed relaxed and happy.
"There was lots of laughing," the source said. "Jake and the girl were totally comfortable with each other. Jake
had a huge smile the whole time."
Gyllenhaal's rep would not comment on the relationship.
