However, after they reportedly broke up, Aaron posted a sappy message about Shailene on his Instagram page.
"thanks for letting me chase after you the first couple months after we met, and finally letting me catch up to you and be a part of your life. Thanks for always having my back, for the incredible kindness you show me and everyone you meet, and for showing me what unconditional love looks like, I love you and am grateful for you."
Then, the couple was seen out in Los Angeles together ... further adding to speculation they were still together or they rekindled the romance after splitting.
Now that Aaron and Shailene attended the wedding together ... it seems very apparent they're very much still together.
