LeAnn Rimes is recovering after undergoing a minor surgical procedure earlier this week.

Though she failed to elaborate on exactly what procedure she had, the 29-year-old singer complained of "mouth and jaw pain" when opening up about her recovery Saturday.

"K, coming clean….I had minor surgery this week and I've been in SO much pain it's not even funny," she wrote on her Twitter page. "Nothing major just annoying! Pain pain go away!!!!!! When it's mouth pain and jaw pain it makes your whole head pound! YUCK."

On Saturday afternoon, it seemed Rimes was in better spirits, and spent the day lounging around in a bikini poolside with pals. "The pain is subsiding finally for a moment," she wrote. "My head has been vibrating all day. Maybe the sand under my feet is helping."

After her day on the beach in Malibu, Rimes again hit Twitter to exchange inside jokes with none other than Kim Kardashian.

"Let's all go swimming," Kardashian tweeted to Rimes, who responded "I'll go swimming w/ you anytime. People have NO idea what we're talking about, too funny xoxo."
