She was hassled by a rude stranger throughout her entire flight on Friday.
And Sophia Bush had a message for the "creepy" man she had dubbed "Random Dude on a plane," taking to Twitter to share an open letter that she had penned following the incident.
The 34-year-old did not mince words as she scolded the man for his actions, writing: "You do not get to harass me, or any woman, because you think you pay our bills. You don't bro, I DO."
Sophia had tried to keep to herself and just enjoy her flight at the start of the weekend, but one unnamed passenger made the experience miserable for everyone.
Later that day she shared a long note on Twitter, captioned with a middle finger emoji, calling the man out for his inappropriate behavior.
"When you make a woman so visibly uncomfortable, that after you've ignored all visual cues to please leave her alone (one word answers, she pulls out a book, puts on a hat, she actually asks you to not speak to her with the tone and words you're choosing to use) that she finally GETS UP and MOVES SEATS, leave her alone," she wrote.
"Do not continue trying to make conversation," Sophia advised, continuing: "Stop turning around and looking at her. Stop leaning out of your seat and towards her body when she has to grab something out of the overhead bin above her original seat, and sadly also above you, mid flight.
"And in my case, stop believing that you are entitled to make me uncomfortable because you 'watch my TV show' so I owe you some magical debt.
"I make it, you watch it. After that, the 'exchange' is done," Sophia explained, following the frustrating encounter.
However, despite her horrible experience, Sophia upheld her positive, friendly demeanor, chatting with fans on Twitter.
One fan had taken a selfie with her at the airport, and after posting it, Sophia responded: "nice to meet you! Thanks for being so sweet."
