Lauren Conrad Hangs With Derek Hough but Says She's "Single"

Reality star plays coy when asked about that Dancing With the Stars romance rumor

We're on to you, Lauren Conrad.

While she told E! News yesterday afternoon she was single, guess who she turned up with a few hours later at a hotel in Hollywood? Her rumored paramour Derek Hough...

"[I'm] single, having fun" Conrad said at yesterday's Veuve Clicquot polo match at Will Rogers State Park in Pacific Palisades.

She continued having fun later that day at the third annual Haunted Hayride kickoff event in Griffith Park with pal Jamie-Lynn Sigler.

But then it was time for some Dancing With the Stars hotness.

The maybe-couple was spotted outside the Hollywood Roosevelt Hotel chatting with friends, including Hough's DWTS pal Mark Ballas, according to X17. Although there was no major PDA, Conrad and Hough left together hand in hand, hopping into a white Mercedes and taking off with Hough behind the wheel.

A source close to the couple says, "They are cute together."

Hough, 26, avoided talking about his love life last week when E! News asked him about Ms. Conrad.
