While the on-and-off romances of the Jonas Brothers may have you questioning their commitment skills, rest assured they're still gentleman no matter how long a girl is in the picture.
"They open doors and pull out chairs for us to sit in," costar Nicole Gale Anderson tells RadarOnline.com in an exclusive interview.
"They're huge gentleman." They're also huge stars, and their new Disney sitcom Jonas will only contribute to their well-mannered empire.
"It's about three boys who try to balance their rock star lives with their everyday normal lives. So one minute they¹re meeting the Queen of England and the next minute they have this huge test that they have to worry about passing," Anderson says.
Speaking of tests, 18-year-old Anderson recently gave Nick Jonas some advice on getting through school while juggling fame.
"He was worried about passing the California High School proficiency exam," Anderson tells RadarOnline.com, "...I was telling him about my experience and letting him know that he has nothing to worry about because the math portion was really hard for me too and I passed."
On Jonas, Anderson plays Macy, a fan obsessed with the band. Anderson claims to be a huge klutz, constantly falling and hurting herself with occasional help from the boys.
In one Jonas scene, Anderson and Joe are wrestling over a book that the rocker wound up accidentally dropping on her face. "So now I have a scar on my face from Joe Jonas. It's really tiny and pretty faded."
No wonder they're working overtime to open doors and pull out chairs.
