As for Hailey, she posted a now-deleted underwear selfie where she WASN'T wearing her ring.
Okay, before fans panic, it's very likely that a) this was an old photo that Hailey posted, b) she had her ring put away for safekeeping or c) she just didn't like the pic so she deleted it.
All very plausible.
Besides, Hailey took to Twitter not long after her engagement to express her gratitude.
"Not sure what I did in life to deserve such happiness but I am so utterly grateful to God for giving me such an incredible person to share my life with! No words could ever express my gratitude. "
