Miley Cyrus rocked one of her most covered-up outfits ever, yet the casual ensemble was still plenty controversial.

The 23-year-old singer posted a selfie to Instagram on Sunday, showing off a ringer tee that featured the last name "Hemsworth" across the back.

Yes, as in Liam, her rumored on-again fiance.

It seems the "Can't Be Tamed" singer was all about making statements on Father's Day. She also showed off her toned tummy in a sheer, long-sleeve white crop top that featured "GRL PWR" hearts over her boobs.

"F**k yes!" she captioned the Instagram. "Girl power on daddy's day!"

Neither Miley nor Liam, 26, have confirmed that they officially rekindled their relationship a few months ago, though there have been plenty of telling signs that they're back on.

Earlier this week, the pair were spotted holding hands during a date night at Soho House in New York City. Liam was in the Big Apple to promote his new movie, Independence Day: Resurgence, which hits theaters Friday. The pair looked equally as sweet as they made their way through LAX after a visit to Brisbane, Australia, in May.

Miley's dad, Billy Ray Cyrus, has even hinted that he might officiate his daughter's wedding to the Hunger Games star. On a visit to the Today show, the proud papa told Kathie Lee Gifford and Kota Hobt, "They're really happy together right now."

And let's not forget that we've seen Miley rock her engagement ring quite a few times since January, including during last month's appearance on The Tonight Show and at a fun night out with her sister, Brandi Cyrus, at a New York Knicks game.

A shirt may not be a permanent way to take the Hemsworth name, but the singer did get matching ink in April with Elsa Pataky, Liam's sister-in-law who's married to his big brother, Chris Hemsworth.

How's that for blood sisters?

Miley and Liam actually have matching tattoos as well. Both wear quotes from Theodore Roosevelt's 1910 speech, "Citizenship in a Republic," that they got in July and October of 2012, respectively. Way more permanent than an item of clothing, no?

Let's just consider Miley's very '90s tee one more tease in the are-they-or-aren't-they saga that we pretty much know the answer to already.

In fact, last month, Liam claimed people will "figure out" what his relationship status is with Miley. While it seems we already have, it's worth hearing the hunky Australian actor tell you himself:
