Audrina, 34, confessed that she was having a hard time during a spa day with Heidi, 32.
"I’ve been going through a lot on the personal side of things with court and custody, just everything at once," the swimwear line designer admitted.
She continued, "It’s been so hard lately. You get so used to having someone there all the time and then it’s getting used to being there on your own and being a single mom. It really hit me today.”
Audrina and her BMX cyclist ex are parents to daughter Kirra, 3. The MTV star was awarded primary custody of her child in November 2018.
"My little girl is my pride and joy and she literally is, like, an angel sent from God. I could cry. I love her so much," Audrina gushed in her confessional.
"I think that Audrina is in a really vulnerable, fragile state. She has a lot that she's dealing with and it does remind me and make me so thankful for the awesome marriage that I'm so blessed to have with Spencer," Heidi said.
