Kaley is actually such a great actress.. this girl has always nailed her roles 🙌

[@navylaks2]

And she shoulld have been Captain Marvel

[@honestchris7472]

Kaley has been in the business for about twenty five years and has played drama as well as comedy. I think that she is a brilliant actress, she has learned her trade and is so convincing in every role that she takes on.

1:13 her talking about Johnny is so cute. Little did she know they would date after 14 episodes in 😂

[@Darkangel-A-c8z]

They had a secret relationship in real life, so when Penny and Leonard kiss in the Halloween episode it's their first kiss in real life, as a couple, as well.

"johnny is the cutest thing in the world. he is so cute he is just delicious" ahhhhhhhhhhh

[@LucasCra]

[@YC_001]

[@traffite3276]

[@averybaxter9521]

I loved her on charmed

[@pennyhofstadter]

2:13 is hilarious

[@SuperGianfrank]

KALEY CUOCO è formidabile interpreta la sua parte con partecipazione tale che sembra realta non finzione artefatta che trapela da attori poco esperti , essendo giovane fara cariera e diverra una attrice piu famosa di adesso con BIG BANG THEORY

1:12 they’re on the wrong floor. Look at the door number

[@JudeMcBride]

Is there a full version of the tour of the apartments on set?

[@deleong72]

Kaley esta igual de hermosa todos estos años sigue igual

[@nagendrareddy815]

But I never saw Howard in that dress

[@TubenIt83]

I think that this is from a rehearsal. That’s why they are not in costume.

[@Jav089]

My apartment is pink and.... It was a mess....

[@tomy5868]

[@josefmanga]

I can understand why they thought Kaley's too young, she's 11 years younger than Johnny Galecki.

[@jasonmyers8600]

She has such a lovely soft voice.

[@MIGUELCHENOISTA]

She has a lovely soft everything

[@TubenIt83]

I wonder if she and Johnny had started secretly dating by this point.

[@wandersonvitor3054]

No, it seems they started dating after Episode 14 from Season 1.

[@mojhoo5860]

I can't imagine any person playing Penny

[@Jeffreeeeey99]
