Heather Rae Young can't want to officially become a stepmom or "bonus mom" to fiancé Tarek El Moussa's two kids.

El Moussa shares Taylor, 10, and Brayden, 5, with his first wife Christina Anstead, and has worked hard at making sure his blended family remains strong.

In a reflective post on social media, Young revealed she bonded quickly with Taylor but it took longer to get close to Brayden.

"I feel so lucky to have these little sweet hearts in my life," the "Selling Sunset" star wrote.

"I’ve been close with Tay from the beginning, it took longer for me to build a bond with Bray, but now we are besties," she added. "If you would have told me 18 months ago I’d be a bonus mama AKA (soon to be step mama) I’d say yeah right."

The 33-year-old Realtor concluded. "I committed 100% from day one & I am so thankful I listened to my gut & my heart because now I have a family."

The couple has started planning their 2021 nuptials but they aren't going to make it a huge affair because of the ongoing coronavirus pandemic.

"We don’t want to have a super big wedding, but our small wedding is probably gonna be someone else’s big wedding, so we’ll see how things go," said the star. "But we’re planning on doing it far enough out to where hopefully the pandemic settles down a little."

Meanwhile, Young confirmed she's picked out her rehearsal and wedding dress. Young said that Galia Lahav designed the gown, which she's already chosen.
