If there was ever a celebrity Halloween costume contest this year, Kate Hudson is clearly winning it.
The 35-year-old actress held her annual Halloween party Thursday night, choosing a super-sexy Sons of Anarchy get-up that had plenty of jaws dropping.
Rocking a studded leather collared crop top, tiny shorts, thigh-high boots and accessorizing with fingerless gloves and a cap, it's safe to say all eyes were on Kate's incredible abs.
... Seriously, she's giving Jennifer Lopez a run for her money!
And keep in mind that both women have given birth to two children -- Lopez to twins Max and Emme, 6, and Kate to sons Ryder, 10, and Bingham, 3.
But it's not hard to see where Kate's good genes come from -- her mother Goldie Hawn, 68, also got in on the Halloween fun Thursday night, and looked fabulous in her own Sons of Anarchy get-up while posing with Kate and her pals.
"Mother of Anarchy is taking her daughters to a little party.... #HappyHalloween @hudsonjeans_pk #hudsons #partytime," Kate wrote on Instagram.
In September, Hudson commented on her famously slim body, stressing that she'll "never" have an eating disorder.
"I won't have girls -- even if it is just one or two who care -- thinking that," she said to Red magazine about constant tabloid speculation on her weight. "Because it's a serious sickness, not something to plaster on the cover of a magazine. And I am the opposite."
In May, ET's Rocsi Diaz talked to Kate Hudson at the launch of her workout company Fabletics' Spring 2014 collection. Check out Kate in her exercise element in the video below!
