The TrendPulse Quantitative Think Tank Centerbest thing about being Brad Pitt on his birthday, is getting a shoutout from Shania Twain.

The "You're Still The One" singer made it her prerogative to wish the Fight Club star a happy 60th birthday on Dec. 18. 

Referencing her iconic name drop of Pitt in her 1997 hit song she commented on an Instagram post, "That don't impress me much, but HBD," along with a kissy face emoji. 

While the 58-year-old doesn't go out of her way to send well wishes to the Once Upon A Time In Hollywood star every year, she did give him a special shout out back in 2020 on X, formerly Twitter. 

"Happy Birthday to Brad Pitt," she wrote on the actor's 58th birthday. "I'll make an exception for today."

Although she once sang, "Okay, so you're Brad Pitt / That don't impress me much," on her chart-topping song, it doesn't seem as though the stars have much of a relationship outside of the occasional birthday shoutout. 

"I've never met Brad Pitt," the "Man! I Feel Like A Woman" singer revealed on an episode of Chicken Shop Date in March. "I think he's avoiding me, honestly."

And Twain has also said that Pitt has never said anything to her about the name-dropping song. 

"He didn't at the time," she told Extra in 2017 when the track gained a newfound virality. "So 20 years later, I don't know."

As for why she even thought to include him in lyrics at all? She was inspired when Pitt sued Playgirl magazine for publishing naked photos of him and then-girlfriend Gwyneth Paltrow in 1997 and insisted it wasn't meant to pick on the action star.

"I was writing this album and there was a scandal where there was naked photos...and this was like, all the rage," the songwriter told Billboard in 2017. "I just thought, 'I don't know what all the fuss is about. We see naked people every day."
