From the leopard sweater to the leather pants, can you believe that Sharon Stone is going to turn 54 in less than two months!?

The actress was spotted entering a medical building in Beverly Hills on Tuesday afternoon, and we're not sure if she was getting a checkup or a consultation for something cosmetic, but everyone stopped to stare as she strutted down the sidewalk.

But hey, even though she looks two decades younger than she really is, she's not immune to wrinkles:

Doesn't every mom put on a fancy purple dress and black suede boots to do a few errands with their kids? We think not, but then again, there's only ONE Sharon Stone!

The Basic Instinct beauty spent the day with her boys Roan and Laird ... who are off from school for Christmas break.

Looks like the 53-year-old actress still has a spring in her step!

Sharon Stone has no problem keeping up with her three young sons ... Roan, Laird and Quinn.

The Basic Instinct actress, 53, ran across the Beverly Hills street with her growing boys ... and the group ended up at Pinkberry for a sweet treat.

Ms. Stone is definitely an actress that seems to know the secret to aging well. Gorgeous!

One glance at Sharon Stone and you forget she's 53!

The Basic Instinct actress headed to the Tavern in Brentwood looking absolutely fabulous in a black dress, sexy stockings and wickedly wild stilettos. Guess she was so busy getting her chic ensemble ready, she forgot her bra. Talk about a killer instinct for fashion!

Ms. Stone seems to be in the best of moods following lunch with friends. Why wouldn't she be smiling? If we were rockin' that kind of bod at her age, we'd be grinning non-stop, too.

Sharon Stone is selling her enormous Mediterranean Beverly Hills estate for a cool $9 million.

The secluded mansion features 7 bedrooms, 8.5 baths and sits on 4.85 acres. Also featured ... covered parking for 14 cars, a massive master suite with dual bathrooms and dressing rooms, a meditation garden and tennis court.

The Basic Instinct star bought the property in 2006 for $10.995 million. Although she'll be losing close to $2 million on the sale, we have a feeling the gorgeous actress will manage.

A stalker was arrested outside of Sharon Stone's Hollywood Hills house Thursday morning.

An LAPD spokesperson told X17:

“Today around 10:30 a.m., the LAPD West unit responded to actress Sharon Stone’s house for a man yelling and banging at the gate. He was detained for mental evaluation.”

The police source says the man was in his 50s and "no one was hurt" in the incident. They did not know if Stone was home at the time, but she has been in New York City recently working on the upcoming film Gods Behaving Badly.

This is not the first time Stone has had to deal with a strange man trying to break into her house - the actress filed a restraining order against a mentally ill stalker named Bradly Gooden last February.

Sharon Stone is 53 and looking fabulous!

The Basic Instinct star sizzled in a skin tight red dress while out to dinner at Boa Steakhouse in West Hollywood.

Ms. Stone will be starring in the upcoming flick Waco which will depict the 1993 stand-off between the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives ... and David Koresh, the leader of the Branch Davidian cult.
