She wore a form-fitting red low cut dress with her long brunette hair in waves, while her beau sported a pink suit, white sneakers, and a wide-brimmed hat for the occasion.

Eagle-eyed fans jumped in at the chance to comment on Leah's "glowing" appearance as many believe that the pair are expecting their first child together.
One person bluntly wrote: "Bump bump bump."
While another agreed, writing: "I'm calling it now... she's pregnant."
The MTV star has repeatedly denied chatter that she is pregnant with her fourth child after viewers initially thought they spotted a "baby bump" in her sexy New Years' Eve photos.
NEW YEARS 'BUMP'
Leah posted a bunch of pics from her festivities with her boyfriend and some friends as they rang in the new year.
In the snaps, the couple packed on the PDA as they held each other close in intimate positions, like Jaylan’s hand on her thigh as she pushed him against the wall.
In others, they kissed to celebrate entering 2022 with one another and snuggled together on the couch.
The Teen Mom 2 star stunned in a velvet black dress with a plunging neckline and high slit up one leg.
Some fans, however, were zeroed in on her slightly extended belly as they wondered if she has a bun in the oven.
“OMG!!! Is she pregnant,” one asked, while another added: “Looks like a baby bump.”
A third noted: “She does look pregnant and he has his hand on her tummy in one of the pictures.”
'DISRESPECTFUL'
Leah attempted to shut down all speculation the following day by sharing the "daily insights" from her pregnancy calendar in an Instagram Story.
In the snapshot, one of the categories stated: "Chance of getting pregnant."
The chances appeared to be "low."
The star captioned the post: "Some of y'all's comments are disrespectful as f**k."
She also addressed the rumors during a virtual interview with Headliner Chicago last month where she laughed off the comments.
"Listen, there's only so many times you can say that somebody's pregnant."
She joked that Jaylan tells her to "ignore" the comments pointing out a potential baby bump as she countered with a smile: "No, I want to let them know, I was bloated last week. That was not okay!"
Leah is already mom to daughters, Ali and Aleeah, 12, who she shares with ex Corey Simms, and Adalynn, eight with ex Jeremy Calvert.
