LAS VEGAS, NV -- Only in Vegas.

Hillary Clinton met with pop-star Britney Spears while campaigning here on Thursday ahead of Nevada's Democratic caucus on Saturday.

"Being in Vegas for #PieceOfMe is amazing for so many reasons...Especially when you get to meet @HillaryClinton!" she tweeted, referring to her "Piece of Me" concert in Vegas.

"Such an inspiration and beautiful voice for women around the world!!!" she added on Instagram. "This woman had an intense presence and I felt very honored to meet with her!!!"

Despite the excitement, it appears Spears has come just short of an official endorsement.

The singer originally included Clinton's official campaign hashtag -- #ImWithHer -- in her caption on Instagram, however she later edited the post to remove it.
