The 27-year-old actress teased her fans with a series of posts on her social media pages over the Easter weekend (25-27Mar16) hinting at a new relationship with the actor, who is 31 years older than her.

The first post came on Good Friday (25Mar16), when Jessica shared a shot of a man's hand on her legs with the slogan "There's a new man in my life..." along with the caption: "His hands are wise and tell a thousand stories... #smitten #hatersgonnahate."

She then posted a picture of two bowls of ice cream, writing: "You say sugar daddy but I say ice cream daddy! Lol (laugh out loud)."

Jessica followed her pictures with a video clip, which showed her saying: "No, I haven't been hacked. I'm just really excited to be able to finally share this secret with you guys," before then sharing a snap of what looks like a diamond engagement ring.

Following her posts Jon revealed the two are dating by posting a picture with Jessica on Sunday (27Mar16) captioned: "Easter with my bunny, @jessicalowndes". He added several heart emojis.

However, a source has now told the two are working on a secret music project together and are not actually dating.

"She's glad people are believing it," the source says.

Jessica and Jon have previously worked together on an episode of Hawaii Five-O.
