Lisa Rinna has gone under the knife to reduce her infamous pout! The star, 47, admits to injecting silicone into her upper lip back in 1986 ... a procedure she has regretted ever since.

Rinna, who is getting ready to launch her reality show Harry Loves Lisa on TVLand with hubby Harry Hamlin, tells People:

    "My lips started to define who I am. That bothered me. I took a big hit for being honest. It gave everyone online permission to lambaste me. It hurt my feelings."

Now that the surgery is complete, Rinna says her upper lip is no longer "bumpy and uneven ... my lip has no lumps! It's smooth."

Doctors say that her recovery will take six months to heal completely. The timing for the surgery seems a bit ironic considering her reality show is around the corner. Do we think it's a shameless attempt to gain press for the show? Our lips are sealed.
