BROCK Purdy’s volleyball star girlfriend has been spotted standing by his emotional father’s side while they celebrate the 49ers player’s first win as starting quarterback.

Jenna Brandt appeared to make her relationship with San Francisco’s new 22-year-old secret weapon official with a heartwarming post in November where she called him “my boy.”

Brandt, who played as a setter on the University of Northern Iowa’s volleyball team, was seen celebrating a bombshell win for the San Francisco 49ers.

Purdy led the team to victory Sunday night against the Patriots – leading fans to question the abilities of NFL veteran Tom Brady.

The former Iowa State player’s family and close friends were seen emotionally celebrating the 35-7 win when he ran up to the stands to hug them.

Brandt was seen all gussied up in 49ers gear in a heartwarming video where Purdy ran to hug friends and family after the win.

While Purdy has publicly said little about his personal life, the new starting quarterback can be seen smiling warmly in several pictures with Brandt – a kinesiology major from Sumner, Iowa.

“No way you’re dating THE BROCK PURDY,” someone commented on Brandt’s most recent post on Instagram.

The volleyball star appears to be a part of Purdy’s entourage now, as she and his sister Whittney attended the game in San Fran alongside his family, according to Instagram stories posted by his sister.

According to the UNI website, Brandt is a sports star in her own right as she played in all 31 volleyball matches in her latest season, achieving a career-high in assists as a setter.

Purdy’s on- and off-the-field wins come after his family was reportedly very excited to attend the game – but not for the reason you might expect.

NFL insider Adam Schefter tweeted that the Purdys had not traveled to see many games this season, but this one was different.

“[The family] made plans to travel to this one today well in advance because of… Tom Brady,” the American sports writer said.

However, in a shocking twist, his family got to witness a victory against the seven-time Super Bowl winner that left his father in tears, an emotional video from the 49ers shows.

Purdy had a lot to prove this season.

He was selected as the final pick in the 2022 NFL Draft, earning him the title of “Mr. Irrelevant” – a nickname given to every player who has ever been taken as the 262nd pick.

However, his time to shine came when starting QB Jimmy Garoppolo suffered a serious foot injury that left him out for the entire season.

Purdy entered a game against the Dolphins days ago as the relief, having only made one other appearance so far this season.

He was immediately effective, inspiring his team to a 33-17 win to go 8-4 on the season.

In the process, Purdy ended one of the longest curses in NFL history.

His touchdown pass to Kyle Juszczyk was the first regular season score ever thrown by a “Mr. Irrelevant.”

Now celebrating his first win against an NFL legend, Purdy remained humble, saying it was a “dream come true.”

“It’s crazy. I grew up watching him, seeing him make plays and win Super Bowls,” the 22-year-old told FOX after the victory.

“So, to be out on the same field and being able to compete against one another, it’s literally a dream come true.

“Very blessed, and I’m honored to play against him.”

The U.S. Sun has reached out to the 49ers for comment.
