Dave Grohl's wife Jordyn Blum seen without wedding ring as she plays tennis in first outing since baby scandal

The Foo Fighters frontman's wife Jordyn Blum is keeping calm and carrying on amid his cheating scandal.

Jordyn was spotted in Los Angeles on Tuesday without her wedding ring as she played tennis with her coach, Christopher Crabb following husband Dave Grohl' s cheating scandal.

The duo worked on her back swing and played for four hours on the court. Jordyn was seen wearing a sweat-stained gray tank, red purse and a black tennis skort for the outing. She kept her eyes shaded with large sunglasses.

Fall Out Boy band member Pete Wentz was also playing the sport alongside Jordyn.

The former Nirvana band member also at one point accused his wife of having a "flirty" relationship with the tennis instructor. Christopher also trains A-listers such as Hilary Duff, Zach Braff and Steve Carell.

Her day out was the first time she has been seen since Dave announced on September 10 that he fathered a daughter outside of his marriage and admitted to being unfaithful.

Jordyn and the rock star married in 2003 and share three daughters together. Dave also allegedly had a 15-year-long affair with adult star "alt goddess" Annaliese Neilsen during his marriage.

Jordyn was reportedly surprised when she discovered that the musician was unfaithful to her, as he said he is working to earn her trust back again.

"She was shocked when she found out about the baby, a source told People , adding that her friends are "like family, and they rallied around her."

The insider explained that Dave's "flirty behavior" has been a "hurdle in their marriage."

"It's been hurtful to Jordyn," they said. "We keep reading over and over again how heartbroken everyone is because Dave was supposed to be the 'good guy', the rockstar that didn’t have to do those rockstar things. And people are crazy about the guy, but there is a rockstar side."

Earlier this month, Dave took to Instagram and revealed his indiscretions . "I've recently become the father of a new baby daughter, born outside of my marriage. I plan to be a loving and supportive parent to her. I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness," he wrote at the time.

Both the identity of the woman he had the affair with, as well as the name of the child, have yet to be disclosed.
