Iggy Azalea is staying tight-lipped about cheating rumors surrounding her fiancé, Los Angeles Lakers star Nick Young, instead choosing to make Sunday's iHeartRadio Music Awards a girls' night with pal Demi Lovato.

"We're gonna sit together. We're messing up the seating arrangement," the rapper told ET on the red carpet. "I think it's more fun to make it like, a girls' thing or a friends' thing. It's just more fun, more laughs."

Lovato and Azalea -- who was still wearing her engagement ring at the awards show -- have been pals since teaming up on "Kingdom Come" last year, and Lovato introduced the 25-year-old rapper's performance of "Team" at Sunday's awards.

Last week, Azalea even revealed that she's been pushing for her friend's beau, Wilmer Valderrama, to propose so the two can be betrothed buddies.

"She needs to get engaged. Wilmer needs to get on it," Azalea said on 92.3 AMP Radio's Shoboy in the Morning. "He's slippin'. Have you seen Demi? She's bomb. I don't know what he's waiting for... Listen, you better buy Demi a ring. I want to be engaged together."

Earlier this month, Azalea, 25, announced that she was pushing back her wedding with her NBA star fiance to accommodate the upcoming tour schedule in support of her upcoming album, Digital Distortion. While the couple has yet to comment on the status of their relationship amid cheating rumors fueled by a video secretly recorded by Young's teammate, D'Angelo Russell, the rapper says the album and tour are still on as planned.

"I have tour plans for late in summer and the end of the year, which I'll announce soon," she revealed. "[The] album [comes] out in June... I do have high hopes for a big summer."
