PHOTOS: Big Sean and Jhene Aiko as Paulie and Juno from the movie ‘Juno’ for Halloween

Big Sean and Jhene Aiko as Paulie and Juno from the movie ‘Juno’ for Halloween.

The couple took inspiration from the movie Juno, posting a shared photo on Instagram depicting Aiko dressed as the title character Juno MacGuff (played by Elliot Page on film) and Big Sean as Juno’s boyfriend Paulie Bleeker (Michael Cera).

Matching the movie poster, Aiko showed a profile view of her baby bump with an orange and white striped shirt, camouflage jacket and plaid skirt over jeans. Big Sean wore Paulie’s track outfit, complete with striped socks, yellow shorts and yellow sweatbands.

Instead of the title Juno at the top of the photo, it instead read, “Jhené.” The couple captioned their post, “🧡🎃Happy Halloween 🎃🧡.”

PEOPLE confirmed in July that the couple is expecting their first baby together after Aiko was spotted sporting a baby bump while walking with Big Sean in Beverly Hills. A representative for Aiko said at the time that the pair “is overjoyed and looks forward to this next chapter.”

After the news broke, the “What U Doin?” rapper wrote on his Instagram Story, “Whole new motivation foreal! Very grateful God continues to bless us, Thank you.” He also posted that he “can’t wait to be a dad.”

It was reported in early July that Aiko and Sean were expecting their first child together (Aiko also shares a 13-year-old daughter, Namiko, with her ex, O’Ryan). The pair confirmed the news with a short and simple statement to TMZ, saying, “The couple are overjoyed and look forward to this next chapter.” The “Mercy” rapper later revealed during a concert in Los Angeles that they were going to have a baby boy. Sean and Aiko have been on-again, off-again since 2016. Over the years, both of the singers have spoken out about their relationship. During an interview with Billboard, Aiko referred to Sean as the love of her life.

On Instagram, Aiko posted a photo of herself and Sean recreating the poster for the award-winning film. In the photo, Aiko is dressed as Juno herself, who was played by Page. She donned jeans, a plaid shirt around the waist, a striped t-shirt, and a camouflage-print jacket. Just as in the original poster for the 2007 film, Aiko stands to the side so that her baby bump was fully on display. Sean stands to her side, dressed as Michael Cera’s Paulie Bleeker, complete in his Dancing Condors gym gear.

“The friends that I have become family,” she said. “I don’t have a bunch of friends. I literally have like two friends outside of my blood relatives. Everyone else that I call a friend is literally related to me by blood. So, Sean has become my family. I don’t know what the future holds, but as far as my life goes right now, yeah, he’s ‘L-O-M-L.'” Back in 2016, Sean also described his relationship with Aiko while chatting with Billboard. He told the publication, “Jhené is more than just a friend. I don’t know how else to describe it — me and her are just cool like that. I love her and I know she loves me. I was down to make that commitment — something that will last and be different from the rest.”

The couple — who first met in 2012 — have collaborated on music projects and have dated on and off since the release of their album Twenty88 in 2016.

In August, Big Sean shared photos to Instagram from when he brought Aiko — along with her 13-year-old daughter Namiko Love, whom she shares with singer O’Ryan — to his hometown for a visit.
