'Bachelor in Paradise' Star Lace Morris Is Keeping 'Grace' Tattoo and the Ring

"Bachelor in Paradise" star Lace Morris is back on the market but she's absolutely certain about one thing -- the matching tattoo she got with ex-fiance Grant Kemp ... ain't going away.

Lace tells us even though she and Grant both got their couple name, "Grace," inked on their wrists, she's planning to keep it because it's not just about her ex and the broken engagement.

Lace says it's a reminder of good times she had with Grant, and memories of shooting 'BiP.' She says she always intended to get a tatt souvenir for her time on the show ... just so happens it ended up being about Grant when they got together.

We're told Grant's not rushing to remove the ink, but he's open to erasing it later. Translation: When a new hot chick wants it gone, he'll lose it.

As for the engagement ring -- reportedly worth almost $100k and bought by production, NOT Grant -- Lace says she's keeping it, unless producers demand it back.
