Joe Jonas Joins 'Hot in Cleveland' Cast!

Just when we thought the TV series "Hot in Cleveland" couldn't get any hotter -- Joe Jonas will be turning up the heat! The teen sensation will debut on tonight's show as Valerie Bertinelli's son!

"When they asked me to be a part of it I was thrilled," said Jonas during "Extra's" behind-the-scenes interview. "It's because you got to be my son," Bertinelli teased.

Was the TV mom able to keep the news of her TV son from her family and friends? "I actually didn't tell anybody because I didn't want everyone going, 'Can I come on the show?'" Bertinelli explained, adding, "Everywhere you go you hear about the Jonas Brothers!"

Watch Joe, Val and Betty White at 10 PM PT tonight on TV Land.
