Shirley MacLaine’s still got it.

The 82-year-old screen legend appeared on Sunday’s Academy Awards with Charlize Theron, following an appreciation of MacLaine’s classic film “The Apartment.”

Hollywood’s Dolby Theatre erupted in applause for MacLaine, and she rewarded them with a charm offensive that eventually made her a top trending topic on Twitter.

“Nurse, prepare the immortality serum for Ms. Shirley MacLaine,” one user wrote.

“Shirley MacLaine is wearing a sequined pantsuited [sic], the only variety of pantsuit not owned by Hillary,” said another.

There was also a lot of love for the banter between Theron and MacLaine.

“This is a 4-hour award show, and still I’ll never mind 2 minutes of Charlize Theron alone in a movie theater raving about Shirley MacLaine,” another tweet read.

Oscars 2017 Red Carpet Looks, Ranked From Worst to Best (Photos)

See TheWrap's ranking of Oscars fashion at Sunday's Academy Awards, from Alicia Vikander to Taraji P. Henson.
Teresa Palmer
There’s way too much going on in the look from “Hacksaw Ridge” star Palmer -- unflattering pleats, a confounding fit and odd hair and makeup to boot.

Jessica Biel
Gorgeous as she is, this Kaufmanfranco gown and matching Tiffany statement necklace on Biel is a flat-out disaster.
Alicia Vikander
Last year’s Best Supporting Actress winner needed a bit more support before she stepped out of the house -- black frilly lace, pearls and a curious top-knot.

Karlie Kloss
Sure, Kloss makes her living by showing up and looking gorgeous -- but this looks awfully familiar, if not identical, to Gwyneth Paltrow's Tom Ford gown in 2012.

Dakota Johnson
The "50 Shades Darker" star landed an archive Gucci gown that photographs much better than it looked live walking down the carpet -- several Wrap staffers also remarked on her lackluster hair.

Kirsten Dunst
This Dior Couture creation is both flattering and dramatic with a modern twist -- sewn-in pockets.
Getty Images
Michelle Williams
Williams has always had a more romantic red carpet style -- but this Louis Vuitton gown is oversimplified to a fault. As an ambassador the brand you'd think they'd put a stronger look forward.

Halle Berry
This Grecian-inspired Atelier Versace gown gives Academy Award winner Berry the goddess vibe she's worthy of -- with a wild mane to match.
Getty Images
Emma Roberts
Not only is this Armani collection gown a nice '30s throwback, the dress was made from entirely sustainable materials.
Getty Images
Taraji P. Henson
The Best Actress nominee for "Hidden Figures" is a vamp of epic proportions in this Alberta Ferretti number.

Mahershala Ali
The "Moonlight" star looked sleek in all black -- all the better to complement his Oscar gold, as Ali won Best Supporting Actor.
Getty Images
Auli'i Cravalho
Cravalho, the voice of Disney's "Moana," gets her real-life princess moment in this stunning pleated creation with cinched waist and full train.
Getty Images
Pharrell Williams
The “Hidden Figures” music mastermind never disappoints with his personal style -- and breathes some much-needed life into Oscar menswear. Only possible downside to this tricked-out tux is its designer -- Meryl Streep enemy, Chanel.
