If the month of January alone is any proof, then yes.
It appears the stars just can't stop posting busty Instagram selfies, with the latest being 34-year-old Newsroom actress Olivia Munn.
"Chance's first time on a photoshoot ❤," Olivia captioned this shot of her holding her dog and sporting a ridiculously low-cut black NastyGal one-piece.
... But we doubt anyone's looking at her dog.
Orange Is the New Black star Laverne Cox, 30, got in on the action with this swimsuit selfie she posted on Jan. 1, sporting a plunging swimsuit.
"The Jacuzzi was so relaxing," she wrote. "Maybe I will think to take a selfie when I am actually in the jacuzzi or pool but I usually am too busy relaxing. #VacayIsLovely."
Another confident star is 39-year-old Tara Reid, who obviously has no problem willingly showing off some major cleavage, even after her infamous 2004 wardrobe malfunction exposed her botched plastic surgery.
Clad in a black bra and white jeans, Tara referenced her trophy wife character in 1998's The Big Lebowski while bowling, writing, "#bunnylebowski just got a strike."
Never one to miss an opportunity to show off her slim physique, Paris Hilton, 33, posted this scandalous pic of herself in an open bathrobe on Jan. 2.
"#SpaTime in Vegas," she captioned the pic.
But the most controversial recent cleavage-baring Instagram shot definitely goes to 17-year-old Kendall Jenner, thanks to her underage status.
As if she needed any more plastic surgery rumors
to deal with, Kylie posted this super-racy photo of herself in a low-cut tank top on Jan. 7, which had plenty of people questioning her ample cleavage.
