Julianne Hough didn't just look hot at the Safe Haven premiere in L.A. Feb. 5 -- she was feeling hot, too! "I had a 102-degree fever," the actress admitted to Us Weekly during her Sole Society launch party in L.A. Feb. 7. "It was pretty tough but I'm good. I'm a trooper!"

The blonde starlet certainly didn't look ill, posing like a pro alongside her boyfriend, Ryan Seacrest, and her onscreen love interest, Josh Duhamel. Hough donned an Alberta Ferretti dress, Giuseppe Zanotti heels and Martin Katz jewels for the event.

The former Dancing With the Stars pro has been under the weather several times in recent months. "I've been sick four times since November," Hough revealed. "This is the last one, I think! Too many planes!"

Hough, 24, also addressed the pressure to wed Seacrest, 38, her love of nearly three years. "It's funny. I think so many people are so concerned if we're getting married of not, we're like, 'For real? What's happening?' So now we're just playing along, making people think something."

TV host Samantha Harris recently told Us Seacrest had asked to be set up with Hough numerous times -- and apparently, she wasn't the only one. "A lot of people had tried to hook us up for many years -- for probably four years -- before we got together, but timing was just everything," Hough explained. "I was finally single and it just kind of worked out."
