‘Big Bang Theory’ Star Kaley Cuoco Puts the Squeeze on Christine Baranski in Behind-the-Scenes Look (Photo)

Star of CBS sitcom gets a grip on her colleague

Get a grip, Kaley Cuoco.

Oh, wait, never mind — it looks like you already have one.

With her CBS sitcom rapidly coming to an end, “The Big Bang Theory” star Cuoco took to Instagram on Thursday to share a behind-the-scenes look at the series.

And it was quite the touching behind-the-scenes look, both physically and emotionally.

In Thursday’s post, Cuoco shared a photo of herself and “Big Bang Theory” guest star Christine Baranski embracing each other, a look of intense emotion on Cuoco’s face.

“Don’t miss tonight’s all new episode @bigbangtheory_cbs ! ONLY 3 LEFT!!!,” Cuoco wrote of the image, adding, “my last chance to squeeze the fabulous Christine Baranski!!!”

According to CBS, on Thursday’s episode, titled “The Maternal Conclusion,” Leonard (Johnny Galecki) is pleasantly surprised when his mother Beverly (played by Baranski) comes to visit and she’s genuinely kind to him, until he finds out the real reason she’s there.

Sounds like a fitting episode in the run-up to Mother’s Day.

“The Big Bang Theory” is set to end its run with an hour-long series finale on Thursday, May 16 from 8 to 9 p.m. ET/PT.

Until then, see Cuoco’s behind-the-scenes glimpse below.
