Filming a new project? An early April Fools' Day joke?! Jessica Lowndes and Jon Lovitz are head over heels in love with each other . . . or maybe not. The stars are sparking romance rumors with the PDA-filled photos they've been sharing on social media within the past couple of days.

The stunning 90210 alum, 27, began to tease about her allegedly new love interest Lovitz, 58, on Tuesday, March 22. She posted a photo of red roses and petals spread out on a bed in the shape of two hearts on Wednesday.

I LOVE itz 🌹❤️💋

Lowndes continued the possible charade on Thursday. She drove "his" car and gushed that "being happy never goes out of style." She even posted a risqué photo of her "new man" touching her leg.

"No, I haven't been hacked. I'm just really excited to finally share this secret with you guys," Lowndes said in an Instagram video. The following day, she posted a pic of an engagement ring with no further details.

Lowndes and the Saturday Night Live alum didn't go public until Easter Sunday. Lovitz filmed the brunette in bed and posted a photo of the twosome in his vehicle.
