Brittany Mahomes wears a red miniskirt and knee-high boots at the Chiefs-Raiders game

Brittany Mahomes dressed her baby bump in Chiefs red as she supported her husband at his latest game!

On Sunday, October 27, the 29-year-old Kansas City Current co-owner stepped out in style to watch her quarterback husband Patrick Mahomes and the Kansas City Chiefs take on the Las Vegas Raiders at Allegiant Stadium in Las Vegas.

The expectant mother of three showed her team spirit by wearing the Chiefs' red and black colors. Her chic game day look consisted of a red miniskirt paired with a matching red shirt jacket, which she left unbuttoned to reveal a black tank top underneath – and her growing belly. She accessorized with black knee-high boots and styled her hair into an updo with pieces that framed her face.

In a photo posted to Instagram by Tavia Hunt, wife of Chiefs owner Clark Hunt, Brittany is seen in her red and black outfit while holding her daughter Sterling, who was equally stylishly dressed. The three-year-old wore a denim outfit decorated with athletic patches and her dad's No. 15, and tiny red boots with ruffled ankle trim. She also had a Chiefs-patterned bow in her hair for added flair.

Before kickoff, Brittany and Sterling were seen giving Patrick some love. Photos showed the trio hugging and Brittany giving her husband a sweet kiss for good luck. It appears the lucky smooch paid off, as Patrick reached a major milestone during the game, making NFL history as the fastest player to reach 30,000 passing yards (in just 103 career games).

The Chiefs celebrated the achievement on their official Instagram account, writing: “30,000 more reasons to love @patrickmahomes. Congratulations, QB1!”

Brittany, who announced back in July that she and Patrick, 29, were expecting their third child together, has been no stranger to putting together some Chiefs-inspired maternity looks this football season.

Just last week, she wore a customized denim jacket with “Mahomes” written on the back and 15 – Patrick's jersey number – on the bottom as she stopped by Levi's Stadium in Santa Clara, California, as the Chiefs defeated the San Francisco 49ers 28-18.

Brittany completed the look with brown boots and a silver handbag, which she paired with black sunglasses and a white ribbon in her hair.

Earlier this month, Brittany even channeled Britney Spears while attending the Kansas City team's game against the New Orleans Saints (which they also won 26-13). In a post shared to Instagram, she showed off her Chiefs red leather pants and matching jacket – a throwback to the leather catsuit Spears, 42, wore in her “Oops!…I Did It Again” music video.

“Monday night ❤️,” Brittany captioned the post, which included four photos of the former soccer player posing in a leather look.

In addition to her more glamorous outfits, Brittany has also chosen to flaunt her baby bump more. When the Chiefs took on the Los Angeles Chargers at SoFi Stadium in LA in September, she wore a bold red baby T-shirt that she cradled her stomach in and sporty, leather-like track pants with buttons down the sides.

To complete the look, she wore a hat that read “Mahomes 15” and sneakers that also featured Patrick's jersey number.

At the Sept. 22 game in Atlanta – where the Chiefs also picked up a win – Brittany opted for a comfy look in an oversized iridescent gray Chiefs t-shirt with shorts underneath and paired the look with bright red cowboy boots and a red black Chanel bag.

Brittany has also been flaunting her bump this year with the help of some famous friends — most notably her friend and Chiefs tight end Travis Kelce's boyfriend, Taylor Swift.

Earlier this month, she showed off her baby bump on Instagram with fun new snaps from the Chiefs game – and her friends Swift, 34, and Lyndsay Bell joined in on the photos.

Brittany is seen smiling with her friends on either side, while Swift sips her drink and cradles her friend's stomach to her left. To her right, Bell held a beer in one hand and touched her stomach with the other.

“Same girls, new belly🥹❤️,” she captioned the post.
