Dave Grohl and his wife, Jordyn Blum, appeared happy just before he had a child with his mistress.

The Foo Fighters frontman, who revealed his indiscretion on Tuesday, was photographed in apparently cheerful mood with his wife at Wimbledon in London on July 2.

The long-time couple were able to laugh all day long as they watched the women’s singles first round match from the coveted Royal Box seats alongside other celebrities.

Grohl, 55, and Blum, 48, chat, cheer and laugh throughout the tennis tournament, but they don’t appear to show any form of public involvement.

For the outing, the rocker paired a navy suit with a white shirt, a gold patterned tie, and brown Dolce & Gabbana shoes.

Blum, for her part, wore a suit-inspired ensemble featuring a pleated tea skirt, which she paired with a cream handbag and matching peep-toe heels.

The blonde beauty styled her hair in a low braid and both she and her husband completed their look with black sunglasses.

It’s unclear when Grohl’s fourth child was conceived or born; he and Blum have daughters Violet Maye, 18, Harper Willow, 15, and Ophelia Saint, 10.

“I recently became the father of a baby girl, born out of wedlock,” he announced on Instagram on Tuesday.

“I plan to be a loving and supportive parent to her. I love my wife and my children, and I will do everything I can to earn their trust and forgiveness.”

The former Nirvana drummer, who did not reveal the woman’s identity, concluded his message by saying he and his family are “grateful” for the public’s “attention” to all the children involved as they “move forward together.”

Grohl and Blum, a former model and now MTV producer, met in 2001 at a bar in West Hollywood, California.

“When I first met my wife, we went on a few dates and I decided I wasn’t ready for a serious relationship, so I just stopped calling,” he told Elle in 2007.

But “after three months,” the musician says, “he had an epiphany and called her back.”

“She picked up the phone and said, ‘Oh, I never thought I’d ever hear from you again,’” he told the outlet.

The couple married in August 2003 in a ceremony at their Los Angeles home. Last month, they celebrated their 21st wedding anniversary.
