Kelli Giddish reveals Taylor Swift's kind gesture for Law & Order: SVU cast while filming Emmys skit

Law & Order: Special Victims Unit star Kelli Giddish is revealing the sweet gift Taylor Swift gave the cast as she filmed her cameo role in a skit for the Emmy Awards.

Giddish, 46, plays Amanda Rollins on the popular show and told the Women in Entertainment podcast that Swift, 36, made 'really good cookies' for the actors on set.

'She brought me some really, really, really good cookies,' Giddish reveals in the upcoming September 22 episode. 'And I'm kind of a cookie snob, so I was really pleased.'

The actress revealed that 'they were sourdough brown butter chocolate chip.'

Giddish describes the overall experience as 'so fun,' telling the podcast hosts how everybody was 'so happy to host her.'

The blonde bombshell also revealed that Mariska Hargitay, who hosted Monday night's Emmy Awards, may have taken some of her advice for the skit.

'Mariska told me about it, and I was like, "Can she be holding her cat? That's my only request,"' Giddish continued. 

'And then she actually brought her cat.'

It's well–known that Swift's cat Olivia Benson is named after Hargitay's character in the show.

With a high-profile guest visiting, Giddish admitted that things felt a little different on set that day.

'It was great. It was like the President of the United States was visiting, you know, like security was crazy,' Giddish added.

'And the thing is, she comes in, and she's totally just sweet, down to earth, like a beautiful, beautiful spirit.'

The skit poked fun at her fanbase's zealous decoding skills.

The singer played an NYPD rookie opposite Law & Order stars Mariska Hargitay and Ice-T as they attempted to crack the 'big question' - 'Will Taylor Swift be at the Emmys?'

The skit immediately started trending online and a mysterious clue Swift uttered sparked speculation she was hinting at new music.

'In order to crack a Swiftie case, you gotta think like a Swiftie,' Hargitay, in character as Olivia Benson, told her team. 'Because the Swifties think that everything is a clue to what she'll do next.'

Hargitay then pulled out a bulletin board filled with clues and a red string connecting them together. 'Ok a crime board, now we talking,' Ice-T said.

'So let's start with the Emmy nominations. Abbot Elementary, nominated for seven Emmys. Season six premieres this year. Seven and six, add 'em up people,' she said, before Law & Order actress Kelli Giddish replied, 'Taylor's lucky number, 13.'

As Hargitay continued deciphering the puzzle with her team, Swift walked in, suited up with a badge on her hip and coffee mug in hand.

'Hey guys,' Swift says. 'This isn't adding up.'

'Who asked you, rookie?' Ice-T says.

'Our perp has a clear M.O. A lot of this doesn't fit the pattern, and I don't think everything is a clue.'

'I think what we're gonna be looking for is hiding in plain sight,' Swift - wearing her wedding band and massive diamond engagement ring from Travis Kelce - said.

Cryptically, she says straight to the camera: 'Saccharide, Aries, from the vineyard, North or South.'

The team furrow their brows in confusion and Hargitay asks, 'What did you say?'

'I didn't say anything,' Swift replies.

'Rookie's weird,' Ice-T says.

As the scene continues to unfold, Swift heads to the crime board to plead her case.

'Why would she be showing up to the ceremony tonight? She's probably going to be sitting at home playing with those cats she's named after TV show characters,' Swift, holding her Scottish Fold cat Olivia Benson, said.
