Kellan Lutz and Annalynne McCord are definitely back on after their split! You wouldn't take someone to your brother's wedding (with all your family) if you aren’t sure about your relationship, right?

This past weekend the hot couple were spotted at Kellan's brother's wedding, where Kellan was the best man. Annalynne looked super comfortable mingling with the Lutz family and friends.

According to Hollywoodlife.com, Annalynne also hosted the bachelorette party for the lucky bride. Do you think she’s trying to win the family over?

Wonder if they'll last this time around.
