Another reality-series romance is brewing between a couple of celebs!

Former Calvin Klein underwear model and soap opera stud Antonio Sabato Jr. and singer Blu Cantrell are more than just clowning around on NBC’s newest competition show Celebrity Circus, a source exclusively reveals.

“They’ve been getting close and hanging out after rehearsals,” said the insider. “Antonio seems smitten with her.”

Celebrity Circus, which premieres tomorrow, pits a group of celebs against one another as they try to perform crazy-ass stunts, including high-wire walking, fire dancing and doing acrobatics in the wheel of death. Other contestants include Brady Bunch star Christopher Knight, Olympian Janet Evans, Jason "Wee Man" Acuña, Rachel Hunter and Clueless actress Stacey Dash.

And we may soon get a look at what Sabato Jr., 36, may be seeing these days. Cantrell, 31, recently shot a spread for Playboy after dropping upwards of 25 pounds since she began training for Circus.

Sabato Jr.’s rep didn’t comment on the possible romance, but said, “We do know that all of those competitors have become such a tight-knit and close family.”

However, a rep for Cantrell said of the two, “They are having fun right now.”
