Just three months ago, the 57-year-old was seen packing on the PDA with adult movie star James Deen at a Hollywood event, suggesting her romance with Robert was a whirlwind one.
But the couple certainly looked loved up as they posed for engagement pictures together at the Four Seasons hotel in Beverly Hills on Thursday.
Janice was clearly ecstatic as she proudly pointed at her huge diamond while her arm was wrapped around her husband to be.
