Eminem seemingly paid subtle homage to his late mother, Debbie Nelson, during a performance on Saturday.

The record producer rapped “Without Me” at the Abu Dhabi F1 Grand Prix five days after his mom’s death at age 69.

The song, notably, includes the line, “F–k Debbie.”

While many of the Grammy winner’s fans yelled the expletive while singing along, Eminem remained noticeably silent.

Besides this omission, the songwriter has yet to publicly comment on Nelson’s passing since news broke last week.

The mother-son duo infamously had a contentious relationship, which Eminem demonstrated in many releases over the years.

In addition to “Without Me,” Nelson is referenced in “Cleanin’ Out My Closet.”

In the 2002 song, Eminem claimed he witnessed his mother “poppin’ prescription pills in the kitchen” and referred to himself as a “victim of Münchausen’s Syndrome … made to believe [he] was sick.”

Eminem, whose birth name is Marshall Mathers, subsequently lost a defamation lawsuit to his mom over the song.

In 2015, the Oscar winner released “Headlights” and acknowledged he had “hurt” her the “worst” with what he wrote in his music.

It is unclear where the pair stood before Nelson lost her battle to advanced lung cancer.

She did hint at a reconciliation in 2008 while speaking to the Village Voice.

Nate wrote via Instagram that he felt “hatred and mixed emotions” after Nelson’s passing.
