"When your best friend is dying to know what your babies name is and she keeps guessing and can't figure it out," Cuoco captioned the image, "so she sends you this LOL."

On Thursday, the Big Bang Theory star shared a mirror selfie in which she wore sneakers, thick socks and a knee-length pale lavender halter dress.

Posing with her bump, Cuoco, who is expecting a daughter, joked, "I think I'm officially showing LOL."

Last month, the pair enjoyed some football with Pelphrey's family on Thanksgiving, posing in matching New York Giants jerseys and holding a matching baby onesie to go along with them.
