Sienna Miller may have never achieved household name as an actress, but if you toss out the male-female double standard and give credit where its due for bedding the best and brightest A-listers, then Sienna is a living legend.
Yes, the official list now goes:
Chamberlain, Nicholson, Brando, McQueen, Hefner ... Miller.
Actually, there are two Millers, because Arthur Miller deserves utmost props for banging Marilyn Monroe as a playwright.
Anyway, Sienna has conducted high-profile relationships with Jude Law, Tom Sturridge, and Balthazar Getty (who was married at the time, but we're not here to judge).
Back in late 2015/early 2016, it was rumored that Miller dated Ben Affleck following his split from Jennifer Garner.
The two filmed Live By Night together, and sources say they really hit it off on set.
But either the relationship fizzled or it never really began, because Ben and Sienna went their separate ways not long after they finished promoting the film.
But it doesn't really matter, because these days, Sienna's got bigger fish to fry.
In fact, she's reportedly been getting cozy with the most coveted newly-single fish in the sea.
According to UK tabloid The Sun (so take this with all the grains of salt), Sienna is dating Brad Pitt.
Sources say they're not flirting, not hooking up, not canoodling (whatever the hell that means), but full-blown dating.
An insider tells the publication that Sienna is giddy with excitement, but keeping things under wraps for the sake of Brad's privacy:
“It’s early days, but they are very into each other and enjoying a carefree, casual summer romance," says the source.
"They’re both absolutely determined to keep everything under wraps. Their goal is to explore things without any massive publicity. It could all fizzle out, so they’re waiting to see.”
It's worth noting that multiple tabloids claimed Brad was getting back together with Jennifer Aniston like two days ago, so you really have to wait and see with these rumors.
But Brad and Sienna would make a lot of sense.
(Certainly more so than Brad and Jen, what with Jen being married and all.)
And hey, even if Brad and Sienna only hooked up once, she's still basically cemented her place as this generation's most stone cold lady pimp.
Feel free to proceed to the comments to inform us of how wildly offensive the term "lady pimp" is.
