Blake Shelton may be single, but he’s not quite ready yet to mingle.
“He’s putting energy into his music and his health,” says one friend. “He is still the person making everyone laugh. He’s always upbeat.”
Blake – who’s been looking noticeably slimmer – has also still been spending time on his beloved Tishomingo, Oklahoma ranch (which he shared with Lambert during their marriage) when he can.
“Obviously Miranda isn’t there any more, but he still has a love for his ranch and his animals,” says the friend. “When he has time, he spends it there.”
In late August, Blake also set aside a few days for some fun with his friends. With a group of guys, Shelton headed to Cancun where he relaxed and partied at the ME Melia resort.
“Blake had a fun weekend and enjoyed his single life,” says a hotel source. “He had fun with girls and seemed to enjoy the attention.”
For now, though, sources say Shelton’s not ready to date and is “focusing on himself.”
“I think he’s open to another relationship in the future, but just not now,” says the friend. “He’s friendly with everyone, but he’s not carrying on with women. He’s taking time for himself right now.”
Adds another insider about the prospects of another relationship:
“Certainly no time soon. He just got divorced, so he’s not thinking about that.”
