Kristen and James both attended the Toronto Film Festival for their movies "On the Road" and "Spring Breakers" over the weekend, and they reportedly ran into each other at a party at the Soho House. According to Today News Gazette, James and Kristen were "laughing and flirting," and he even invited her out to dinner.
James is definitely a big fan of Kristen - back in June he wrote an entire blog post gushing about how great she is after seeing her in "Snow White and the Huntsman." He praised her strength and willingness to take risks, dubbing the actress a "warrior queen" deserving of a crown. So if Kristen is in need of a rebound, she knows who to go to first.
But she's not the only celeb that has recently sparked romance rumors. Here's a look at a few other stars' relationship reports:
Has Rob found a rebound, too? Hollywood Life reports that Rob and Zooey had a nice little chat after running into each other at the Soho House in West Hollywood on Friday. Ultra-feminine Zooey is the complete opposite of K-Stew, so maybe she's just the type of girl Rob needs to get over Kristen (if he is trying to get over her). Rob and Zooey do share a love of performing songs, so maybe they'll make sweet music together soon.
Demi Lovato and Niall Horan
Speaking of musicians that make cute couples, it looked like Selena Gomez and Justin Bieber were about to get some competition for their top teen pop couple crown when Niall and Demi went out on a date to Pink Taco after the VMAs. The One Direction singer seems pretty smitten with "The X Factor" judge, but he might be headed for heartbreak - a source told Perez Hilton that Demi has her eye on her ex Wilmer Valderrama and that "it's only a matter of time before they get back together."
Meanwhile Wilmer's ex-fling Minka might be back together with her ex Chris Evans after briefly dating "The Avengers" star in 2007. The sexy pair was spotted checking out "The Book of Mormon" in New York City on August 24.
Since some celebs seem to be having a hard time staying away from their exes recently, maybe there's still hope for Robsten.
