Britney Spears' Boyfriend Sam Asghari Makes Subtle Christina Aguilera Dig, Deletes It

The '00s rivarly between Britney Spears and Christina Aguilera is a thing of legend and as much as they both want to put it in their pasts, it just won't die.

While the two pop stars themselves have spoken out about making peace, Britney's boyfriend just chose sides with some subtle shade.

During a Q&A on his Instagram stories Wednesday night, Sam Asghari was asked, "Britney or Christina?" It should come as no surprise who he picked, but he did it in a very Mariah Carey/"I don't know her" way.

His response: "Christina who?" Sam later deleted the post.

Speaking with Jimmy Kimmel earlier this year, Aguilera said, "When I was coming up, it was very obvious, you know, me and Britney were definitely ... there was the Britney/Christina considered rivalry thing," She added, "If we had social media back then, we would have probably done a song together and just squashed it."

When Kimmel pressed them on doing something together now -- adding "I would like to be a part of it" -- she said, "It's probably not too late, Britney. I am down. If her reps say okay."

Other tidbits gleaned from Sam's Q&A: "Sam" is short for Hesam, he majored in criminal justice and studied physiology in college, said he still has "things to prove" professionally, supports the LGBTQ community and may appear in a movie soon.

When asked about his film prospects, he replied, ""Hold tight. We have great things coming for you :)"

Britney and Sam first met on the music video set for "Slumber Party" back in 2016.'
