It would appear that Lauren is following my prediction from 16 months ago.
I am surprised given how deliberately and profoundly she had attempted to change her body, lifestyle, and attitude about herself. Attached is the most recent media that I could confirm a date on, that being May 14, 2022. For reference this date is almost exactly four years after her extreme reduction, taking her from a somewhat shocking M cup to a modest B (in her own words). By the time of her wedding in early 2021 she had gained back about 2 cup sizes. This interview, in middle May of 2022, shows a fullness not evident just over a year ago.
I made it an animated GIF so that one can see that there is mass and substance behind that top.
She is very close if not slightly larger than her start size on Trading Spaces all those years ago, from which she expanded at about 1 cup a year till 2017-2018 and her reduction. Given the amount of tissue removed and likely reconstruction of her breasts, she will never reach anything close to that. I anticipate that she is reaching her maximum size (post BR) in the next 2-3 years.
I do want to add that current on-line information about her weight loss, diets, surgery, etc. is very chopped up, erroneous in many cases, or simply edited to change her history somewhat. She has used images of herself from just after the 2018 reduction in current social media posts and even her 2008 black bikini images, from after her gastric bypass surgery, have shown up as "current" images of her as recently as 2020. She turns 37 this year.
There is an easy to find photo with her plastic surgeon, not long after the reduction, which really shows how small she went in 2018. Compared to these recent appearances, her 1-cup a year trend is alive and kicking, but unsustainable.
