The Bachelor stars Desiree Hartsock and fiance Chris Siegfried have bonded with fellow alumni Jason and Molly Mesnick since her move to Seattle.
It's not just an ABC-driven friendship of convenience, either: Des and Chris attended the first birthday party for Jason and Molly's daughter, Riley!
Their adorable daughter Riley, we should say.
Jason and Molly, who didn't win her season but famously got together with him on The Bachelor: After the Final Rose special after he dumped Melissa Rycroft, made it last.
Their little girl's milestone last weekend was a big birthday party at their house attended by about 100 family and friends, including Desiree Hartsock and her man.
"I loved seeing Riley interact with all of our friends and family during the party," said Molly, who celebrated her fourth anniversary with Jason on February 27.
"We set up a faux-photo booth and had every guest stop and take a fun photo with props," Molly explained of her young one (did we mention she's cute?!).
"I know she won't remember this party, so I thought the photos would capture great memories from the day and she can see everyone who came out to party with her!"
We're glad to see the family so happy.
