LOS ANGELES, CALIFORNIA: Arnold Schwarzenegger's daughter, Katherine, revealed that she wanted her father to blend in during school drop-offs as she was acutely aware that her upbringing was unique compared to most of her peers. During an episode of SiriusXM's 'The Nikki and Brie Show', the 'FUBAR' star's eldest child reminisced about how the actor used to drop her off at school.

Co-host Nikki Garcia asked, "How was it for you growing up and, like, you had the most badass dad ever; to have someone so buff and strong and then, like, literally the Terminator! Did that faze you at all as a kid?" To which Katherine responded, "I remember the only time really realizing like, 'Okay, this is different,' because my dad would drop us off at school in a Hummer that had no windows, no doors and no roof, and I was mortified."

'Please, I'm so embarrassed'

"He would pull up to carpool and I was, 'Can you please drop me off down the street? Please, I'm so embarrassed. Can we please just take the minivan? Like, this is not my vibe. I just don't like this at all,' " she recalled. Katherine added, "That was really like the only time that I felt like, 'Okay, something here is different.' And then as I got older, the boys in my grade became much more interested in my dad. That was the time where I was like, 'Okay, this is different for me.' "

Arnold, 75, shares four children, Katherine, Christina (31), Patrick (29), and Christopher (25), with his ex-wife Maria Shriver. Additionally, he is also the father of Joseph Baena (25). In the Netflix docuseries 'Arnold', the bodybuilder-turned-actor candidly discussed how fatherhood has had a transformative impact on him. "Becoming a father is a whole new ball game. People talk about it a lot but you have no understanding what they’re talking about. When Katherine was born, there were tears running down my eyes. I was just so emotional about this life that I have just created with Maria and you realize this is a whole other world," he recalled. "It was staggering, what joy they brought to us."

'It's nice to see your kids having kids themselves'

During the premiere of his series 'FUBAR' in May, Arnold spoke to PEOPLE magazine about his experience of witnessing Katherine's journey into motherhood. "It's nice to see your kids having kids themselves and to watch this new dimension,” he said. "You see them growing up and you see them going to school and getting smart and getting their degrees, getting their jobs and all this, but now seeing them be a parent? It's fantastic. It's really great." He added, "It's really fun to watch and hang out with her now and to see the way she'll react to the kids because she is so great with them."
