The Big Bang Theory star sparked baby rumours when she announced that she was taking a “big break” from work in March.
The 32 year old actress also set tongues wagging when she rocked up to a recent awards show sporting what looked to be a tiny baby bump.
“We all think she’s already pregnant,” spilled an insider to The National Enquirer, also noting that Kaley had been on a major health kick recently.
“All the signs are there. Kaley and Karl couldn’t be happier."
The pair announced their engagement via a sweet Instagram video last November.
“It’s been a whirlwind since they got engaged,” notes the source, “and all they talk about is having babies.”
