Jodi Lyn O'Keefe has made a career of playing the mean hot chick -- remember "She's All That" and "Prison Break," anyone? But the 37-year-old beauty is the first to admit that looking this good is no easy task. "I eat like a saint," she revealed to Wonderwall.com during a recent chat about her hit VH1 series "Hit the Floor," which concludes its third season on March 28. Keep reading to see what else she told us about having one of the sexiest wardrobes on television (without showing skin!), perpetually playing the mean girl, her thoughts on the "Prison Break" reboot and more!

Jodi Lyn O'Keefe on the upcoming finale of the third season of "Hit the Floor": "Hang onto your seats because the last episode is pretty fantastic. If you thought it was bad now, just wait. … I'm not allowed to say anything else. I literally have been told what I can and cannot say because everything is a spoiler right now because we're so close to the end. … It's very hard for me. It's really, really hard. I have to look at [notes] all the time before I talk to anyone because it's like, 'Wait a second, what episode are we on? What can I say about [my character] Lionel? What can't I say? What can I say about other characters? I have to do the rundown right before I speak to anyone because sometimes you can spoil things and you don't even know that you've spoiled them."

Miss Lionel Davenport...if you please. #hitthefloor #season3 #SetLife

Jodi Lyn O'Keefe on Lionel's style: "I always said that [her wardrobe] can be sexy without being super-revealing, so my dresses are always to my knee or a little bit lower, and I'm always wearing a half sleeve. So I'm leaving a lot to the imagination, but everything is still really form fitted. I wanted everything to be as classic as I possibly could because for all of the other characters around me, it's all about skin. I wanted to be the opposite of what they were doing. I have these beautiful, amazing, talented dancers around me all day long who are wearing very small costumes, so I wanted to wear as much costume as I could. … It's a different kind of sexy."

Jodi Lyn O'Keefe on being mean: "I actually want to say every terrible thing that Lionel says because it's not me. So I really have fun with it. Every time I get a new script, I'm taken aback by what they have me saying and doing, but I've never once said, 'No, I don't want to do that.' It's just too much fun. I literally roll my eyes sometimes like, 'Oh, Lord, here we go. What's Lionel doing this week?' But I do enjoy every minute of it."

Jodi Lyn O'Keefe on her history with playing mean characters: "It became surprising to me the first time [I was cast as one], and then it really shocked me when I got to do 'Prison Break.' That was the biggest shocker of all. I love it. It's absolutely so far removed from who I am as a person. I'm not confrontational. I would never win in a fistfight -- ever! And yet I'm walking around like I'm kind of a bad ass. And I'm always toting a really large gun."

Jodi Lyn O'Keefe on the meanest character she's played: "When I first started to sink my teeth into Lionel, I thought she might be the grownup version of Taylor Vaughan [from 'She's All That']. … But I'm gonna have to say Gretchen [from 'Prison Break']. She had a soft spot, but she was definitely the meanest. She was a professional assassin. It doesn't get much meaner than that."

Put up your dukes @ikimberlyelise soooo much fun tonight!

Jodi Lyn O'Keefe on how she stays in shape: "Yoga, Pilates and spin classes. That's my thing. Also, whenever I'm working, I kind of eat like a saint. So that's the other thing. And I spend a lot of hours on my feet and a lot of time on set. I try to keep things as clean as possible [with my food], and I drink water like it's going out of style. I'm not a delicate flower -- I'm a lot of girl. It's very easy for me to gain weight and put it on and keep it on and not realize that it's happening."

Jodi Lyn O'Keefe on the 'Prison Break' reboot: "I've been so excited about it because I was a huge fan of the show before I ever joined the cast. I don't know what the story is about, though. … I've said time and time again that I would love nothing more than to show up and get to be Gretchen one more time in my life, so if it happens, great, and if not, then I'll still be watching. [I would come back] 100 percent. It was the best time I ever had in my life."

Jodi Lyn O'Keefe on whether or not she'd return to 'The Vampire Diaries': "If they asked me back, 100 percent as well. I had a really great time there. I started to feel like that cast was becoming my family, and I spent a lot of time with those kids in Atlanta. I loved it. It was really good to be the good guy -- really good. … They reminded me that the show is about supernatural creatures and that I've only died twice and people usually die about 13 times. So I'll look at that as a positive. That show isn't going anywhere anytime soon, so if there's ever an opportunity for me to be a ghost or a flashback or another incarnation of Jo, I would love it."

Jodi Lyn O'Keefe on Jo's shocking death in 'The Vampire Diaries': "That was always [the writers'] plan from the beginning. About half way through, they started to let me know their plan for the season and for Matt Davis' character [Alaric]. … I was pretty devastated. It was really hard to say goodbye to everyone. It was especially hard to say goodbye to Matt Davis because doing the opposite side of that scene and watching him go through the emotion of losing Jo, there were moments when I was supposed to lay there and be dead where I was still crying. It was rally brutal."
