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.
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."
