No, I've never happened upon an astro twin. I think the closest I've had are house placements that are similar...I think strawb. is close with her house placements, but not completely. 

My famous astro twin is Nicole Kidman. She was born the same day, we have the same Moon, same Ascendant, same MC, and Venus in our 10th, although her Venus is heavily aspected in a favorable fashion.

As a Gemini, I've wondered my entire life where my twin was. When I was a little girl, I always felt like there was a part of me missing, somewhere out there in the wide world. Was he/she in China? Japan? Egypt? Right down the street? The older I get, the less I feel my twin's presence. Maybe they're dead? Maybe I'm not supposed to have a twin?

I wish I could like Esther Hicks but it's just too much Neptune and I'm pretty Neptuney myself as a 12th House person.

I have an astro-twin that I went to school with but we are nothing alike, house placements and family influence I guess.

I sometime watch or read spirituality things I wouldn't normally like to admit to in public... Pisces meets Capricorn.  but I do like them.  they make me feel better.  I can often pooh-pooh something and then end up enthralled by it years later. 

So I find myself listening to Esther Hicks.  And after rolling my eyes for years.  So this weekend I thought, hey, I should look at her chart and see why she hits me just right.  Of course:  born on the same day as me (different year). 

So I tell myself, "oh that means nothing!"  and I look up her chart:  same Moon.  And the other placements hit me in all the right places.  all of them. 

We'd probably drive each other crazy. 

Have you ever happened upon an astro-twin?  How about a famous astro-twin?

I do have a real life fraternal twin only 1 minute apart and we never got along unfortunately :/ we love each other of course but we are so alike that we are different and so different that we clash. 

In my elementary school we were 4 girls in the same class sharing the birthday. We weren't close friends, but I keep in touch by facebook. I also have a friend with the same birthday from university, and Beyonce was born the same date & year.

Would that be astro-sextuplets? 

It's fascinating how each life unfolds differently, even when having the exact same transits.

My astro twin is the singer Natalie Imbruglia. She was born 2 days after me, but she in Australia and me on the U.S. West coast, so really we're only a day apart. Sun, moon, and all other planets are in the same position.

I don't know much about her but reading about her life it doesn't seem like she's been married or had long, committed relationships. Same here. I could be projecting.

ETA: just did a Wikipedia check and she was married from 2003-2008, the same years I was in my longest relationship. Hmm.
