The family's annual Christmas party turned out to be quite the event. Kim Kardashian made her big debut after being featured in numerous family snaps, and her husband Kanye West appeared to be in good spirits as well. The rapper suffered from a mental breakdown last month, while Kim was robbed at gunpoint in Paris in early October.

Fortunately, Reign's mama, Kourtney Kardashian, has reconciled with Scott following a year of separation. She and Scott split last year after he was caught partying with an ex girlfriend. Further, Kourtney previously admitted the break up took a toll on her mental health, causing her to suffer from severe anxiety.

"I'm usually really calm but when I'm going through something in my life and when Scott and I broke up, I just had a lot of anxiety," she revealed to Today Extra. "That's when I really stepped up my workouts. Like I would go in some days like shaking. I could almost not even — it was so hard to even start my work out."

According to Life and Style, the couple reconciled just before the holidays, and are already planning for baby No. 4! In addition to little Reign, Scott and Kourt are also parents to Mason, 6, and Penelope, 4.
