Celebrity couples break up for all kinds of reasons and while many move #OnToTheNext, some are left bitter and hung up on their relationship from the past. These exes are like a gnat or a nasty cold — you just can’t get rid of them!

1. Nick Loeb

Sofia Vergara and Nick Loeb's recent (and still ongoing) feud over her embryos is the ultimate "can't get rid of him" ex-story. Loeb reentered Vergara's life in April, after he claimed that she destroyed the fertilized eggs they had stored when they were together. To put it simply: Vergara's ex wants to have her baby, and just won't quit.

2. Justin Bieber

Justin Bieber continues to make it hard for Selena Gomez to get over him. Though the couple has been broken up since 2012, Gomez has always made reference to Bieber still being in her life. Not to mention, the two were spotted hanging out just a few days ago.

3. Ben Affleck

Jennifer Lopez and Ben Affleck's love history reads like a novel. Since their 2004 split, J.Lo has had a hard time getting rid of the "Bennifer" title. In February, the two reunited at the 2015 Oscars, where Affleck flirtaciously whispered in Lopez's ear.

4. Big Sean

It's safe to assume that Naya Rivera can hardly turn on the radio without being reminded of her lingering ex, Big Sean. Fans went crazy when they heard "I Don't Fuck With You," being that it was most likely about the Glee actress. Rumors were also swirling that Rivera had something to do with his split from more recent girlfriend, Ariana Grande. In other words, she'll never get rid of him.

5. Austin Mahone

Camila Cabello would agree that you never forget a first love. The Fifth Harmony singer ended her short, but meaningful romance with Austin Mahone back in November. But recently Mahone threw shade at Cabello, saying that their relationship "wasn't real." Ouch.
