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."
