Country singer Miranda Lambert is enjoying her single life after divorcing Blake Shelton. The “Over You” singer is "having blast flirting," but she does not want to mingle at the moment, Contact Music reported Sunday, citing a source.

Soon after the divorce, the 31-year-old singer got a makeover late August. She dyed her hair extra-blond and accessorized the look with chunky bracelets and neck chains. And now, a source close to Lambert has revealed to Contact Music that she is "having fun" being single.

“She may have lost a husband, but Miranda gained a ... new outlook on life. She's dressing sexier, exercising again and smiling more than ever,” the source said. “She lost part of herself trying to be what Blake wanted. Miranda feels her new look and attitude is just what the doctor ordered. She's having a blast flirting and being single.”

However, Lambert is reportedly not ready to date yet. “Miranda wants to keep working on herself and having fun for now,” the insider said.

Lambert is keeping herself busy following her divorce in July with Shelton, her husband of more than four years. She is slated to appear at the charity event, Cause for the Paws: Back to Basics, in Luckenbach, Texas, on Sept. 18 and 19.

During her performance at a concert in Detroit Lakes, Minnesota, earlier in August, Lambert told the audience that she has been “drinking all day” after the split, according to Perez Hilton. “I deserve it. I just got divorced,” Lambert reportedly said.
