The "Blurred Lines" singer's rep shut down the engagement rumors by saying it was "100% not true."
The two are not yet engaged, but April already has the stamp of approval from Robin's dad, Alan Thicke.
Alan recently gushed about the model at the "Vacation" premiere in Los Angeles. He told E! News, "She's lovely. It's a great time for him. [He has an] album coming out, and April is there and supportive."
Robin and April have been dating since November of last year.
