While taking some time off from ABC's Dancing With the Stars, professional dancer Maksim Chmerkovskiy put his dancing abilities to good use while choreographing Propel Zero's "Drops of Life" commercial in New York.

We can't help but notice how sexy the hunky dancer looks in his form-fitting shirt and jeans. Oh, and did we point out that he's doing the splits? Yowza!

We're getting thirsty just lookin' at him!

Yesterday we spotted Maksim Chmerkovskiy and Hope Solo leaving rehearsals for Dancing with the Stars, and we also caught Nancy Grace, Rob Kardashian and Cheryl Burke sweating it out.

So what's this we hear about Maks and fellow pro Derek Hough feuding behind the scenes? "They hate each other," an insider tells Us Weekly. The boys reportedly squabbled after Chmerkovskiy told DWTS judge Len Goodman to retire the other day, and Derek (who's won the competition three times now) told the mag, "I had a laugh about that [remark] ... I was looking at the plaque upstairs and…well, never mind." Burn!

"The professional dance community is really small. The dancers have known one another their entire lives," the source added. "Now that the group is famous, it's added a whole other level of rivalry and competitiveness."

Dancing With The Stars' Maksim Chmerkovskiy is partnered with Kirstie Alley this season, who has met both praise and criticism for her changing weight.

But Maksim let loose without his partner at Trousdale lounge Tuesday night. Also at the club as of late were Justin Timberlake and Chace Crawford, though all three were with separate groups.

Alley, 60, has been seen out partying plenty lately, especially at Colony nightclub in Hollywood.

Dancing With The Stars fan favorites Kirstie Alley and partner Maksim Chemerkovskiy, stopped by The Ellen DeGeneres Show where they were gifted with much safer Dancing costumes, courtesy of Ellen!

The talk show host gave the stars a bubble wrap dress, vest and pants, so all of their parts will be protected if they fall!

Maksim was so excited, he decided to test out his new bubble wrap vest, but quickly took it off once he started dancing -- thank you Maksim!

Kirstie also left the host with a signed pair of her dancing shoes to auction off for the Gentle Barn, Ellen's pet charity.

Yesterday we spotted Dancing With The Stars hottie Maksim Chmerkovskiy and a few pals brunching at Toast in West Hollywood, and he made sure to show one of his friends plenty of attention in between bites of food. After the tumble he took with partner Kirstie Alley the other night, it looks the two are still getting along great, as evident from the sweet things he's been tweeting at her over the past few days.

So what has Kirstie been up to? We spotted her at Katsuya later that evening, and we love the fact that she's got the confidence to slip into a slinky black dress!

Maksim Chmerkovskiy was spotted in New York City over the weekend, and the Dancing With The Stars hunk sipped on a zero calorie Pepsi Max as he headed home with a turkey. A Max for Maks? But of course!

Otherwise the Dancing With the Stars hunk could've had an Emergen-C! Maksim Chmerkovskiy went out on the town Sunday evening but first made a pit stop on Robertson for a little Vitamin C pick-me-up. Good to know he's taking care of his hot bod while not on the dance floor! Can't wait to see his moves tonight...

Or at least he tried to! Thankfully Brandy had her brother Ray J by her side for protection. The trio dined at Beso last night after Dancing With the Stars. We can't imagine Maksim Chmerkovskiy and his partner will be going home anytime soon... so does that mean Bristol Palin and her gorilla suit are dunzo?
