Just weeks after announcing his split from Jennifer Aniston, 49, sources told In Touch, Justin Theroux, 46, was getting close to Olivia Munn, his gorgeous co-star from 2017's The Lego Ninjago Movie. (She's also a pal of Jen's.) While Olivia, 37, denied romance rumors on social media, one source tells In Touch, Justin "finds her really attractive and has been leaning on her since leaving Jen."

In late March, Parks and Recreation alum Aubrey Plaza and Justin were spotted out and about in NYC before retreating to Justin's West Village pad together. "Justin loves funny, edgy women who aren't uptight," a source says. "Aubrey's like the anti-Jen." Aubrey, 33, has been dating director Jeff Baena since 2011, but according to the source, "You never know what could happen."

And the women keep on coming! Justin and Emma Stone wrapped their upcoming Netflix series, Maniac, in December, but they still can't seem to get enough of each other. They went on a sushi date in NYC on May 2, left a Met Gala afterparty together on May 7, and were photographed hanging seaside at the Hotel du Cap-Eden-Roc in the South of France during the Louis Vuitton Cruise 2019 show.

They even shared a cozy private cabana at one point. Emma, 29, and Justin, who always seems to be shirtless around the Oscar winner, "were very flirty," an eyewitness says of the duo, who were joined at times by celeb pals like Sienna Miller. Though Emma (who also happens to be friends with Jen) has been dating Saturday Night Live writer Dave McCary since late 2017, he was nowhere in sight. "She and Justin love hanging out," a source adds.

Emma wasn't the only star Justin got close with during his time in France in late May, either. The writer-director also was spotted soaking up the rays with sultry 28-year-old Spiderman: Homecoming actress Laura Harrier. "He was quite taken with Laura," says an insider. "They've become fast friends." Another source adds, "He's been socializing like mad with women he's been meeting in NYC and abroad."

The Leftovers star also seems to have a thing for the young ones. Justin became pals with Selena Gomez, 25, when he first began dating Jen in 2011, but they've since developed their own "flirty friendship," says an insider, and have continued to text, talk on social media, and hang out in NYC and LA. "Since leaving Jen," says the insider, "Justin's been having the time of his life."

And there's more! Justin and actress-artist Petra Collins, 25, were spotted together at a Met Gala pre-party on May 7 and out to lunch the following day. An insider says their connection makes sense: "They travel in the same New York art circle. It wouldn't be surprising if the offbeat pair were more than friends."
