Baby on board! Blake Lively, who is pregnant and expecting her second child with husband Ryan Reynolds, showed off her growing 𝚋𝚊𝚋𝚢 bump in a bikini at Taylor Swift’s star-studded Independence Day bash on Sunday, July 3.

The Shallows star, 28, took a dip in the Atlantic Ocean with her hunky hubby, 39, and put her growing belly on display in a tiny two-piece. The second-time parents-to-be — who welcomed daughter James in December 2014 — embraced each other and snuck in a few smooches near Swift’s seaside mansion in Watch Hill, Rhode Island.

The couple were joined by Swift, the pop star’s new beau, Tom Hiddleston, and a slew of other famous faces, including Gigi Hadid, Cara Delevingne, Karlie Kloss and Este Haim, among others.

On June 22, Lively joked about her expanding tummy during an appearance on Late Night With Seth Meyers. Seth Meyers, who just welcomed son Ashe with wife Alexi Ashe, congratulated the Gossip Girl alum on her pregnancy, saying, “And you have a 𝚋𝚊𝚋𝚢 on the way.”

The actress acknowledged her 𝚋𝚊𝚋𝚢 on the way by rubbing her belly, and then said, “Yes, you’re guessing correctly. This is not brownies.”

“I’m one of five kids. My husband is one of four, so we’re officially breeders!” she teased. “You can go on our website, and we will give you some of our children.”
