According to Radar Online, a source close to Kailyn said, “She wanted to go back to Puerto Rico before the baby comes. The boys were with their dads, so she went for a few days.”

The pregnant star has also been using Twitter to document her solo trip, with one tweet saying, “Baby Lo and I just went for our first ocean swim of the summer,” before adding, “I should’ve brought my GoPro so I could be entertained while I’m in the water by myself.”

Just last week, she retweeted, “I want to take spontaneous trips,” and it appears she followed through!

Lowry’s son Lincoln, 3, is with her ex-husband Javi Marroquin at Comic Con this week, and her son Isaac, 7, is with her ex-boyfriend Jo Rivera.

She is estranged from her third baby daddy Chris Lopez but is still hoping for a reunion.

According to an insider from Hollywood life, “Kailyn’s hoping he will change his mind when the baby arrives. She doesn’t care about the financial side of things, as she’s more than capable of supporting her kids herself, but she would love for him to be part of his child’s life.”

In the meantime, soak up the sun in paradise, mama! You deserve a little R&R!
