Heather Rae Young admits she didn't invite Selling Sunset costar Christine Quinn to her wedding to Tarek El Moussa. At the start of the Netflix reality show, Christine and Heather were very close. Despite some tension between the ladies, they seemed to have a level of respect for each other. However, their relationship took a turn for the worst after Christine referred to Heather and Tarek's relationship as the future Heidi Montag and Spencer Pratt from The Hills, jokingly dubbed as "Speidi."

Christine began calling Heather and Tarek "Speidi" after noticing a number of articles online about them baking cookies and watching movies. Heather took offense to her comments and realized Christine wasn't the friend she thought she was. Since then, the two started drifting apart with no hope in sight for a future reconciliation.

In an interview with Page Six, Heather opened up about not inviting Christine to her wedding with Tarek last month. "She did not get an invite to the wedding," the 34-year-old exclusively told the new outlet. "I am big on loyalty, I’m big on friendships and trust, and I do not trust her. I don’t think she’s a loyal person." Despite breaking her trust, Heather, who is having a wedding special, is able to be cordial with Christine as they both work for The Oppenheim Group. However, the relator has no interest in having a relationship outside of work with her. And it seems their feud only escalated through season 4 as Heather recalled a storming out of a party after Christine brought up that they both dated the same guy. Heather thought Christine bringing up her "personal business" was "disrespectful" and "irrelevant in my life."

It was a constant back and forth between the women, and Heather finally hit her breaking point. After noticing one thing after another happening between her and Christine, or Christine and her costars, Heather had enough and cut Christine out of her life. "All this negativity and toxicity, it’s just not healthy," Heather said. "I’m in the most amazing place in my life that I’ve ever been, and I only want people that are going to be positive and uplifting." Christine began hitting below the belt too many times, and Heather had to cut off the friendship in order to be in a healthy state of mind. Despite the end of their friendship, Heather was able to say a few nice things about her former friend. Heather admitted that Christine was great for TV and appreciates her presence on Selling Sunset.

After all the turmoil between Heather and Christine over the years, Heather realized her friendship with Christine was no longer healthy. Heather didn't want someone at her wedding who she no longer trusts or considers a friend. She was ready to move on from that friendship and Christine's absence from the wedding.
