Radar spoke with two top surgeons who believe the 52-year-old Academy Award winner could use some work if she wants to say young like her 42-year-old boyfriend.
Both agree skin tightening is key.
Dr. Pam Agullo tells Radar, "Omg Rene looks like she needs some serious beautification. Her skin is looking lackluster and in need of some tightening, both easily achieved with microneedling with prp and a customized skin care routine."
She also believes upper eyelid surgery could drastically improve the already beautiful star's appearance.
"It would seem like she is also in need of upper eyelid surgery, the excess skin is evident and much more prominent than before," Agullo says, adding that the Bridget Jones Diary actress "would also benefit from a really good haircut and color to bring back the happy to her beautiful face."
Dr. Frank Agullo -- also known as Dr. Worldwide -- reveals Zellweger's weight loss has contributed to her changing looks.
“She has lost weight, which becomes very apparent in the face. She would benefit from volume restoration under the eyes, lips, cheeks and in the nasolabial folds with fat or fillers," he tells us.
Agullo also mentioned skin tightening. "She would benefit from an upper blepharoplasty, her lids are resting on her eyelashes. I would start skin tightening with radiofrequency before she needs something more invasive," he says.
Zellweger and Anstead have been linked since June, which is around the same time he finalized his divorce from Christina Haack.
The actress and her Wheeler Dealers host boyfriend have been inseparable since.
They've also been making out in any place they damn well please.
Zellweger was caught locking lips with Anstead in a Home Depot parking lot. Looking like teenagers, the two barely came up for air and couldn't take their hands off each other.
Despite the experts beauty opinions, Anstead seems to like what he has.
Zellweger was caught moving her stuff into his Orange County, CA home last week, and Us Weekly says, "He adores her and makes her feel safe."
