According to a source close to the 46-year-old beauty, ever since the two first started dating in 2012, they have reconnected during under-the-RadarOnline.com visits to Smart's grandmother's home outside of Ensenada, Mexico.
And the low-key family estate is quite different than what fans might expect of the "Love Don't Cost A Thing" singer!
"The house was actually built by Casper's grandfather and is nothing special at all, but it is one of Jennifer's favorite places in the world," the source explained.
"It is on the bay and every time they go there they have to fill up a big tank with water so that they are able to shower and such," said the source. "Jennifer really enjoys just being able to be free without having to have her hair and make-up all done and be wearing clothes that she really considers to be just a costume."
Now that she and Smart are back on, "They are planning to spend Thanksgiving there with his family in a few weeks," the source revealed.
"All of their relatives on both sides are hoping that this time really works for them because their families would be thrilled if they got married one day."
"She's already met his mother and his grandmother, as well as several of his other relatives. Everyone in Casper's family adores Jennifer and her kids absolutely love him."
