Farrah Abraham has had a pretty rough couple of weeks. The Teen Mom star was arrested for driving under the influence on St. Patrick's Day, and has been defending herself on the interwebs. But she's keeping her head up and spending quality time with her family — make that her baby daddy, Derek Underwood's family!

Derek passed away on December 28, 2009 (just two months before Baby Sophia was born) when he and his friends lost control of their car and it drove into a power pole. Sadly, Derek and his friends were drinking on the night of the incident, and the police said their car hit a patch of black ice after illegally passing someone on the road.

Despite the fact that Sophia never met her father, Farrah's made sure that her little girl knows who her daddy is. She and Sophia frequently visit Derek's grave, and on April 2 they hit up his resting place with Derek's dad, Jerry.

"Soph & I are #roadtrippin today to see Daddy Derek:)" Farrah tweeted. "#WeMissYou!"

Farrah remains close to Derek's dad and stepmom, (they've even appeared on Teen Mom), and recently spent some time with them during the holidays. We're thrilled that Sophia has a relationship with her dad's family!
