SALT LAKE CITY, UTAH: The 'Real Housewives of Salt Lake City' Season 4 star Lisa Barlow's son Jack recently revealed that he would serve his Mormon mission in Colombia Bogota North Mission.

To commemorate her son's significant achievement, Lisa hosted a party. Nonetheless, it's worth noting that one of the cast members, Heather Gay, was not included in the guest list for the announcement party.

Heather wasn't even aware that Jack had received his mission assignment or that Lisa had organized a party. In the most recent episode, Heather had a video chat with Angie Katsanevas, during which the 'RHOSLC' star disclosed the existence of Lisa's announcement party.

Heather and Angie were discussing who all were coming to Whitney Rose's daughter's birthday party. Heather asked Angie if Lisa and Jack were coming to the birthday bash.

However, Angie said, "Did you hear the good news that he's going to Columbia for his mission?" She added, "Lisa did a whole announcement yesterday."

Heather was left stunned as Angie and Whitney were invited to the announcement party. Angie went on to reveal that Lisa had a small brunch.

Meanwhile, stunned Heather said, "an intimate gathering... it sounds of like her best supporters." Heather admitted in the confessional, "This just feels like more of the same rejection I've been experiencing but it stings especially more coming from Lisa."

'RHOSLC' Season 4 star further noted that she would avoid Lisa at Whitney's party as it could lead to an altercation.

Heather Gay and Lisa Barlow feud over Mormonism

Heather Gay and Lisa Barlow had totally different concepts and experiences of Mormonism which often ended up in dramatic arguments. In the previous episode, Heather and Lisa had a heated up exchange as Lisa prepared to send her son Jack to mission.

Meanwhile, Heather didn't want Jack to struggle the same that she had in the past and tried to convince Lisa not to send him which turned into an explosive feud. Heather noted in the confessional that her way of Mormonism was actually different.

She added, "I'd gladly join her church. It seems great. All the perks and none of the payments. Maybe if that's what Jack says on his mission, he'll have a lot of success. We're serving Vida tequila and strapless dresses."

Lisa Barlow expects Jack to serve the mission in New York

'RHOSLC' star Lisa Barlow was expecting her son Jack to serve his mission in 'Europe, or New York'. During the premiere episode of 'RHOSLC' Season 4, Lisa expressed her excitement about the possibility of Jack going to a location where she could shop, like Milan.

She told Meredith Marks, "You know what's going to be really hard? When Jack gets his mission call, he can literally be called anywhere. We can't see him, and he can't come home. I cry every day. I'm like a baby."

However, Lisa has since come around to accepting Jack's placement. Lisa expressed her excitement surrounding his mission location.

She tweeted, "We are soooo happy Jack was called to serve in Colombia." Lisa added, "He loves serving others and was so happy this is his call. He has so many friends that have served here and still are and we are sooo happy for him."

'Real Housewives of Salt Lake City' Season 4 drops on Tuesdays at 9 pm ET on Bravo.
