Reunited! Kate Hudson and ex Derek Hough spotted backstage at Dancing With The Stars

Hollywood is a small town - especially for the young, beautiful and single.

So it came as little surprise Monday when a pair of exes, actress Kate Hudson and Dancing with the Stars pro Derek Hough, were reunited backstage as the ABC dance-fest was filmed in Los Angeles.

The two, who both have had their fair share of celebrity romances, dated through parts of 2014 and 2015.

The Deepwater Horizon beauty wore her blonde hair up in a top-knot.

She wore a long flowing dress with a halterneckline as the DWTS fan stopped by the set, where her ex has long been a favorite pro dancer. 

Her list of past celebrity beaus most prominently include two rockers: her ex-husband, Black Crowes front-man Chris Robinson, with whom she has a 12-year-old son named Ryder; and Muse's Matt Bellamy, with whom she has a five-year-old boy named Bingham.

The daughter of actress Goldie Hawn and singer Bill Hudson has also been romantically linked with You, Me and Dupree co-star Owen Wilson; Parenthood actor Dax Shepard; controversial sports stars Lance Armstrong and Alex Rodriguez; and singer Nick Jonas.

Not to be outdone, dancer Hough has been involved with a bevy of beauties that would make him the envy of any bachelor short of Leonardo DiCaprio.

He has been tied to breathtaking British actress India de Beaufort; American Pie star Shannon Elizabeth; reality TV beauty Lauren Conrad; and The Vampire Diaries Nina Dobrev. 

He's most recently been seen with So You Think You Can Dance stunner Hayley Erbert.

On the night, the gorgeous Hudson, 37, was snapped in a long, billowing white dress, accompanying a female friend with a few children to the taping.

Hough, 31, was clad in a dancer's outfit of a white shirt and black slacks.

Hudson, speaking with shock jock Howard Stern last week, said she's still seeking 'someone really hot' who can make her laugh.

When the 62-year-old Stern suggested Brad Pitt as a potential paramour, Hudson acknowledged the obvious: 'I think Brad is very, very handsome,' adding that her taste in men ranges 'all over the place.'

On Monday, the Utah native Hough showed off his wares on the dance floor, guiding his celebrity partner, Taxi actress Marilu Henner, 64, to a stellar 27 out of 30 points on an evening the pairs dedicated their dance numbers to years that made an impact on their lives.

Henner's Viennese waltz was inspired by the year 1978, in which her beloved mother passed away, as well as her casting on the iconic TV show, which co-starred Judd Hirsch and late stars Andy Kaufman and Jeff Conaway.

Elsewhere on the ABC competition Monday, viewers saw contestant Amber Rose's teary emotional journey through the ballroom in an outtake of her practices with pro partner Maksim Chmerkovskiy.
