The sweet moment was captured on the live feeds on Thursday.
After 26-year-old Angela reportedly revealed to her man that she had a "secret," she told the lifeguard, "I'm in love with you."
"I can't believe we have the same secret," Tyler, 23, reportedly replied.
Angela then admitted, "I can't believe that just came out of my mouth," according to the magazine.
Angela and Tyler began the game in an alliance, and they quickly developed a strong friendship. However, during recent weeks, the pair realized they cared for one another deeply and therefore sparked a romance.
Viewers have watched the couple -- who are ironically both from Hilton Head, SC -- engage in serious conversation about childhood and their families. They are both also incredibly attracted to one another.
But it took nearly two months for Angela and Tyler to take their relationship to a physical level.
While the pair kiss and spend a lot of time together in the Big Brother house, Angela and Tyler are trying to hide their showmance and feelings for one another from their fellow houseguests as to avoid putting big targets on their backs. It's the worst-kept secret, however, because everyone is onto them.
Previously-evicted houseguest Kaitlyn Herman, who had a flirty relationship with Tyler during her short time in the house, admitted she "didn't expect" Tyler and the fitness model to fall for each other.
"I don't know, like, it's interesting. It makes sense. They're both, like, Hilton Head natives, I guess," Kaitlyn told Rob Cesternino last month on his Rob Has a Podcast, according to Us.
"And they are pretty and they work out, I mean, sure, like it's fine. I didn't see that when I was in the house, so this obviously developed recently, since I've left. I can't really give my honest opinion about it because I'm not around them."
