Wow! The single life certainly agrees with Katie Holmes.

Tom Cruise's ex-wife sheds her clothes in a series of sexy shots for a new IRIS jewelry ad campaign.

In other pictures, the mother of one looks equally sexy rocking a bikini in the beachy photo shoot.

But on Thursday, before playing a concert in Macon, Georgia, country superstar Lambert was the one excited to meet someone she adores: reality star Honey Boo Boo.

The "House That Built Me" singer met 7-year-old Alana Thompson, of TLC's "Here Comes Honey Boo Boo," and her family at the venue just outside their tiny hometown of McIntyre, Georgia.

"They are so sweet," Lambert, 29, captioned a snap she posted to Twitter of herself alongside Honey Boo Boo, the pageant queen's parents, June "Mama" Shannon and Mike "Sugar Bear" Thompson, and older sisters Lauryn "Pumpkin" Shannon, Anna "Chickadee" Shannon, and Jessica "Chubbs" Shannon. She even invoked Honey Boo Boo's signature phrases when she wrote, "You'd better redneckognize!"

Kaley Cuoco is on an award-winning show and usually has a great eye for fashion. She revealed her biggest fashion faux pas to People magazine this week at the Most Powerful Stylists Luncheon, hosted by the Hollywood Reporter and Jimmy Choo. The sitcom star admitted that her big bangs at this year's Screen Actors Guild Awards were a huge red carpet regret.

Though they might not have gotten great comments from the critics, she had a big bang theory behind her look. She said the bangs were there to help cover up her black eye and that the bangs are a mistake she won't be making again anytime soon. She joked, "Next time, if you're going with a black eye or bangs, go with the black eye."

Check out this vid to see another reason Kaley didn't take the criticism too seriously.

Charlie Sheen's call for his legions of Twitter followers to pelt his daughter Sam's former school with dog feces and rotten eggs because he feels they ignored her claims of being bullied has the private learning institution on edge about the safety of its current student body.

Ah, young love.

Miley Cyrus and Liam Hemsworth are still taking time apart, but both have reemerged (in different ways) while rumors continue to swirl that they are broken up.
