Well that's an interesting slice of news! Jessica and Ashlee Simpson's mom Tina is engaged to her gardener (and boyfriend) Jon Goldstein, reports Us Weekly.

No wonder Jessica needed a drink last night?! We're kidding … Goldstein isn't just any old gardener -- he is a high-end landscaper who owns Johnny Appleseed Landscaping, a company that has many A-list clients and has landscaped the Bel-Air Hotel, Stella McCartney stores and the Sunset Plaza.

Tina was previously married to Joe Simpson, who is rumored to be gay, for 34 years. Tina and Jon were first photographed together at Jessica's wedding last summer at the San San Ysidro Ranch, where they stayed together in a cottage.

A friend of the landscaper says, “He’s a really nice guy. … He’s always cared about Tina…He’s known them for 15 years and has been a part of their family. He's so happy she said yes! I know he had been planning on asking her for a while."

Jon's list of celebrity clientele includes Anna Faris, Ashlee Simpson (obvi), Jessica Simpson (super obvi), Babyface, Freddie Prinze, Jr., Jenna Fischer, Mark Wahlberg, Sam Raimi, Tom Cruise, Sheryl Crow and more.

If Tina Simpson is going to marry a gardener -- at least he's a gardener to the stars!
