Big Sean and Glee star Naya Rivera announced their engagement in October 2013, only to call it off and split up in April 2014.
A few months later, in October, singer Ariana Grande confirmed that she and Big Sean were dating. After making their red carpet debut at the 2015 GRAMMY Awards in February, Big Sean and Ariana then called it quits in April.
ET caught up with Big Sean at the 2015 BET Awards, where the star opened up about his recent high-profile relationships and breakups.
"Man, you know, I don't plan relationships. They just happen," the 27-year-old Dark Sky Paradise rapper said on the red carpet. "That's all it is. I'm just... I'm just living it. It's no, it's no God, it's no script. You know, we just out here doing what we doin'. Feelin' it out."
However, the "I Know" singer said that no relationship is pointless, and that you can always learn from your decisions.
"It's no mistakes in life, though -- only lessons," Big Sean added.
