Shakira and Gerard Piqué 1
The Colombian cantante and the Spanish futbolero have two children together: Milan and Sasha. Clearly they are in it for the long run, but although they have been dating since 2011, they have yet to get married. Does it really matter, though, since they are obviously already a beautiful family?
Adamari López and Toni Costa 2
Adamari met her Spanish dancer beau Toni on Univision's Mira Quien Baila in 2011 and they have pretty much been dancing together ever since. They are engaged and have a beautiful daughter, Alaïa, together, but still haven't tied the knot.
Aislinn Derbez and Mauricio Ochmann 3
In 2014 they met on the set of the romantic film A la mala and the on-screen romance led to off-screen love. They recently revealed that they will get married this year on May 28th. They are to be wed in Mexico in Tepozotlán, Morelos. How refreshing that a celebrity couple actually let themselves have a long noviazgo, no?
Demi Lovato and Wilmer Valderrama 5
Demi and Wilmer have been keeping each other romantic company since 2010. In Hollywood years, that's EONS. They are not shy about expressing their mutual admiration via social media, but seem to be happy going steady for the moment instead of walking down the aisle.
Enrique Iglesias and Anna Kournikova 6
To say that Enrique and Anna are in a long-term relationship is quite the understatement. The Spanish singer/producer and the his Russian former pro-tennis player girlfriend have been dating for longer that most celebrities stayed married, since 2001. Hey, if it ain't broke why fix it?
Eva Mendes and Ryan Gosling 7
In 2011, Eva and Ryan started dating after co-starring in "The Place Beyond the Pines" and in 2014, they welcomed another co-creation into the world: their daughter Esmeralda. Married they are not, together they remain.
Christina Aguilera and Matthew Rutler 8
Matt was a production assistant on the set of Burlesque where he met Xtina. They have been together since 2010 and got engaged on Valentine's Day of 2014. Although they have yet to marry, they have a daughter together: Summer Rain.
Alessandra Ambrosio and Jaimie Mazur 9
Check this out! Alessandra and Jaimie started dating in 2007 and have been engaged since 2008. How's that for a long engagement? They have two children together and your guess is as good as mine as to when the Brazilian model and California businessman will get around to marrying each other.
