Nadia from Nadia: The secret of Blue Water

Funnily enough, it was probably Justin Timberlake or some guy from an early 00s boyband.

As someone who grew up on Star Trek, Jeri Ryan as Seven of Nine was one of the first I can remember

Heck, she's still a stunner today at nearly 60

I never was one to have much crushes on celebrities (though later it's been easy to get parasocial about streamers and tubers), but earliest thing I remember is noting Makepeace (Glynis Barber) as the most beautiful woman in TV at the time.

On complete fiction, I might say Kitty Pryde. I started reading X-Men (having till then mostly read other Marvel) at a point (in local publications) she was about my age.

That aside, John Byrne's She-Hulk (among other Marvel heroines) may have awakened something in me...

Freddy Prinze Jr. was THE pretty face guy from the 90s. I remember paying attention to him back when he acted in I Know What You Did Last Summer, its sequel and She's All That. I was also infatuated by Chris Evans some years before he went on to play Captain America. Cellular and Not Another Teen Movie are movies he acted that come to my mind

Dempsey and Makepeace was awesome, I loved that series!

I remembered another one of my childhood: Erin Grey in the Buck Rogers movie / TV-series (1979 - 1981):

Claire Danes in the bizarre 90s Romeo & Julet adaption got me good too; I wasn't familiar with the story at the time (being 7) and was used to movies having happy endings so boy did that one fuck me up

It was Mia Sara. When I was 10 I had to stay with my grandparents for a few months, and my grandpa had Ferris Bueller's Day Off on Betamax, and I ended up rewatching it multiple times throughout my 3 months there since they didn't have that many movies. I was 10 at the time, just hitting puberty, and it's the first time that I can recall having any sort of feelings for an actress. But considering she was 22 years older than me, not exactly the healthiest crush xD

The first actress close to my age I recall having a crush on was Hilary Duff, who I watched on Lizzie McGuire when my parents got a satellite dish in 2001. Still looks mighty fine to this day, just did a Sports Illustrated Swimsuit shoot recently, gotta say I still have a crush on her all these years later.

Although now I think Sorsha was hotter I guess my first would have been Brooke Shield's character in Blue Lagoon. I was 4 when the movie came out so I would guess 6 or 7 by the time I was exposed to a little bit of the movie.

Edit- I was not able to watch it all at that age (nor have I now) but it is a pretty messed up story about cousins that are abandoned on an island and eventually fall in love and have a child.  Brookes was only 14 at the time.

Noone in particular really, but I watched Eurotrip like 50 times. Everyone in there gets my vote.
