Jana Kramer Celebrates Fourth of July with Family Fishing Adventure

Fishing trip time!

In celebration of the Fourth of July, Jana Kramer and her fiancé Allan Russell brought the whole family fishing. Wrapped up in a star-spangled towel, the country singer celebrated America while showing off her baby bump.

On Tuesday, the One Tree Hill star, 39, brought her two kids Jolie, 7, and Jace, 4, to the lake. In an Instagram post, Kramer showed off her growing family decked out for the holiday.

In the primary photo, the whole Kramer family smiled wide as Russell, 42, perched his hand on her shoulder. Jolie and Jace hugged their mom and future stepfather, all dressed for a good swim. Kramer wore a neon yellow bikini, which she covered up in an American flag towel, before showing it off in a later photo.

Most eyes were on Kramer’s baby bump. The “Why Ya Wanna” singer announced her pregnancy to PEOPLE in June. In the new family snapshot, Jolie placed her hand on Kramer’s stomach, hinting at her excitement for a new sibling.

Kramer also included several snapshots of her kids, including one showing Jace making a funny face and another with Jolie smiling beside her mom. The final shot showed Jace concentrating hard on fishing while waiting for a fish to bite.

Kramer kept her caption brief but celebratory. “Happy 4th of July ????????,” she wrote.

The post comes three days after Kramer showed off her new baby bump in a lakeside photo for the first time. Kramer was seen paddle-boarding in a bikini, with her son Jace in tow on a trailing float.

“After packing up our house in a week and a half and then learning a movie to filming for 3 weeks all day… this is everything I was looking forward to at the end of it,” Kramer captioned that post. “My kiddos, family and rest on my favorite lake.”

Just a week before these photos, Kramer revealed the sex of her third baby on the Whine Down podcast. “We did the early blood work to check all the stuff and check the gender,” the singer said. “They saw the part, so we are having a boy! Yay!”

While Kramer was excited by the news of her baby boy, she was also surprised. Before the screenings, the country music singer admitted that she “was convinced it was a girl.”

Back in early June, Kramer gave PEOPLE the exclusive first look at her baby bump. After some struggles with fertility, Kramer discussed the joyous surprise of pregnancy. “I didn’t think it would ever happen again, if I’m being honest,” she said. “I’ve been through a lot, so this has just been a really beautiful thing.”

The “I Got the Boy” singer also revealed her fiancée’s heart-warming reaction. “I’m letting it all sink in. It’s everything I’ve wanted and more,” Kramer said. “Allan was so sweet. He wrote me this little sticky note saying, ‘You deserve the happy ending.’”
