Gwen Stefani has been single now for a few months, and for at least a month, the tabloids have been trying to set her up with another Summer of Splits dude, Blake Shelton. It doesn’t come out of left field – they are both on this season of The Voice and they do seem to enjoy each other and like each other a great deal. But up until now, the rumors of a rebound romance have sort of fallen flat, and both Blake and Gwen have laughed off the reports. But over Halloween weekend, they were seen/photographed spending a lot of time together, looking flirty and touchy – go here to see some blurry photos.

As romance rumors continue to circulate around them, Gwen Stefani and Blake Shelton remain adamant about the fact that they’re just friends. However, E! News has obtained exclusive photos of the duo hanging out at Adam Levine and Maroon 5’s Halloween party in Studio City, Calif., over the weekend that seem to show otherwise. In the photos we see Shelton—wearing a rocker wig and headband—holding Stefani close with his hands on her shoulders, eventually moving them down to her waist. At one point he evens ends up with one hand on her backside! In another photo, Stefani—wearing her hair in a bun on the top of her head—is spotted looking up adoringly at Shelton as they chat at the spooky shindig.

Sources confirm to E! News that The Voice coaches spent a majority of the holiday weekend together. First, they were spotted at George Clooney’s Casamigos party on Friday night.

“Blake showed up at the Casamigos party right around the same time as Gwen. It was definitely strange for him to be there because he hadn’t been in years past,” our insider reveals. “They left right around the same time too. Although they were in separate cars when they left, they met up at the next party.”

Though a second source tells us there was no PDA at Clooney’s party, things changed as the night went on. After leaving Clooney’s bash separately, they reunited at Jared Leto’s party later in the evening. Our insider says they were holding hands and eventually ended up leaving his party late in the night together. However, according to another source who works with them on The Voice, this isn’t too far off for the duo, who have been spending more time together as of late.

“They are definitely flirty on the set and you can see they have fun together,” the source explains. “There is something going on between them and they have spent time together off set. They don’t want to label anything or define it, they just really like each other and happen to be going through similar things in their lives. Gwen has spent time at Blake’s house in the Hollywood Hills recently. They want it to stay under the radar and not make it a big public thing because who knows what will happen.”

Yes, of course they don’t want to “make it a big public thing,” that’s why they were cuddling in full view of random people and photographers. Don’t get me wrong, I don’t hate this. It sounds like a fun rebound fling and as long as no one develops feelings, I don’t see why they shouldn’t have some fun. Gwen will not alienate Blake’s fanbase and he won’t really alienate her fanbase. She’s a little bit older and now a single mom. He’s a charming drunk who got seriously burned in his last marriage. This better be a fling and not something more serious.

Speaking of serious feelings, Gwen gave an interview to Carson Daly on 97.1 AMP Radio yesterday and she ended up discussing Gavin Rossdale a bit. She repeatedly said that Daly’s personal questions made her feel like throwing up, but at one point she said: “My life is so extreme right now. My life basically blew up in my face. And now I’m in this new life, and it’s pretty awesome I have to say — I’m so inspired and being back on the show, and just being in a new place. Everything just feels new. I just feel inspired. I don’t know how else to describe it.” When asked specifically about spending more time with Blake, she said: “I was literally that party girl that you hear about when their life blows up, and you’re like, ‘Yeah! I’m going out! Like, watch me!’ We’re just trying to have fun. You know?” Yeah, I get it.
