The Penny look is back just ahead of the Big Bang Theory Season 10 premiere in fall.

Kaley Cuoco has brought back the old Penny look that fans have loved through the years. The actress chopped her chest-level locks into a collarbone-level hairstyle. She shared on Instagram a photo of her back to old Penny-length hairstyle.

The 25-year-old actress also posted some photos on set with her castmates. In one photo, she was seen with costar Johnny Galecki. It was followed by more photos with the rest of the Big Bang Theory Season 10 stars.

It was earlier reported that Cuoco is being resented on set because of her $1 million per episode paycheck. The actress who grabbed the headlines for the wrong reasons also allegedly annoys her co-stars. Cuoco recently divorced her husband, tennis player Ryan Sweeting, and has been in the headlines lately because of her new romance with Karl Cook.

Meanwhile, the Big Bang Theory showrunners have vowed a more hilarious and fun-filled Season 10. More big names are also set to join the already crazy cast of the Emmy award-winning comedy series.

Breaking Bad star Dean Norris will appear in Big Bang Theory Season 10 in a recurring role. He will play Captain Williams, an Air Force officer who will be interested in acquiring Howard (Simon Helberg) and Leonard’s (Galecki) quantum gyroscope. The Walking Dead actress Kate Sagal was also confirmed to join Big Bang Theory Season 10. Sagal will be playing Penny’s mother while 30 Rock star Jack McBrayer will portray her ex-con brother Randall.

Executive producer Steve Molaro also hinted that there might be a fallout between bestfriends Sheldon and Leonard this season. Molaro said the two will be “uncomfortable” with the idea of their parents hooking up and them ending up as brothers.

CBS boss Glenn Geller has also expressed confidence that the show will go beyond Season 10.

The Big Bang Theory Season 10 will air on Sept. 19 at 8 p.m. on CBS. It will be back on its regular Thursday time slot on Oct. 27.
