"Maks wanted a girlfriend. Peta is really sweet and an amazing girl who had a crush on him for a long time," an insider told the magazine.
Though the source admitted the romance is still new, 32-year-old Chmerkovskiy and New Zealand-born Murgatroyd are already said to be serious about one another.
"They are really happy together and having a great time," the insider added.
Chmerkovskiy has previously dated fellow Dancing with the Stars professional Karina Smirnoff.
The couple announced their engagement on New Year's Eve 2008, but ultimately split in September 2009.
Dancing with the Stars airs on ABC.
