Well, what do we have here?!

Jennifer Lawrence certainly played it cool while she was backstage at the 2014 iHeartRadio Music Festival in Las Vegas this weekend, especially when her new boyfriend Chris Martin was close by.

The Coldplay frontman is seen in the background of the latest shot of the Oscar winner as he makes his way on stage to perform in front of a sold-out crowd.

J.Law strutted her stuff and pretended not to notice her beau and walked with her friend toward the side stage to catch the rest of the concert.

The 24-year-old looked fantastic for her big night out in Sin City in an Emilio Pucci studded crop top, black skinny jeans and strappy Valentino heels.

She paired the look with tousled curls, a pink Dior earring (she is the face of the fashion house, after all!) and a metallic pyramid purse.

E! News previously reported that the Hunger Games star was seen walking into the rock band's dressing room before the performance, and was followed by none other than Taylor Swift several minutes later.

The new couple has yet to address their relationship in public, but have been spotted on several romantic dates on both coasts in the recent weeks.

In fact, just last week Lawrence was seen singing along at a private Coldplay concert at the Ace Hotel in Los Angeles.

"She danced the entire time," a source told E! News at the time. "She couldn't take her eyes off him."

Our insider continued, "Jennifer stared adoringly at Chris, both hands in the hair, dancing and singing along to 'Magic.'"

Back in August, the two were seen on a romantic date in an upstate New York vineyard, just days before the actress's birthday.

And then earlier this month, the private duo was seen packing on the PDA at the ultra-hip Chateau Marmont hotel along with a few close friends.

Lawrence and Marin have been dating since at least late June, a few months after the singer and wife Gwyneth Paltrow announced that they were "uncoupling" after 10 years of marriage.
