Smooth moves: Evan Ross sipped on smoothies on Tuesday after a run to Jamba Juice in Los Angeles
He announced Thursday that he and his wife will soon welcome a child together.
And Evan Ross is already going on pregnancy-craving food runs for Ashlee Simpson.
The Hunger Games actor fetched a pair of smoothies from Jamba Juice in Los Angeles on Tuesday.
The 26-year-old son of Diana Ross wore a black wool pea coat over a navy blue sweater and plaid top, camouflage trousers and black sneakers.
He sipped on one drink as he dashed off from picking up the healthy beverages.
However, for the Pieces Of Me expectant mother, the snacks are a stark contrast to the cravings she admitted to while pregnant with her first child, Bronx, now aged six, with ex-husband Pete Wentz.

'I would eat cake, green olives, and tacos,' Ashlee told Entertainment Tonight of her cravings during her first pregnancy.
On Friday, the couple, who married in August at Evan's Supremes singer mother's Connecticut home, was seen holding hands while Christmas shopping at Toys"R"Us in Van Nuys.
The sister of Jessica Simpson, aged 30, bundled up in a fur-collared coat, Ramones T-shirt, high-heeled booties, a Chanel purse, and leggings.

The new bundle of joy will make Evan's diva mother a grandmother for the third time.
Miss Ross (as she once said she prefers to be addressed) has grandson Raif-Henok Kendrick (born in 2009 to her daughter with Motown Records founder Berry Gordy, Rhonda) and granddaughter Callaway Lane (born in 2012 to Ross's daughter Chudney).
On how Diana is as a grandmother, Rhonda previously revealed on the Timothy Hodge show that the legendary singer is equally doting to her grandchildren as she is as a mother:
'It's been so amazing because my mother—some people know, some people don't—my mother is and was a very, very hands-on mother.
'Now she gets a chance to be that kind of a hands-on grandmother. She's so good with my son, it's amazing.'
Hands on: Diana Ross has been described as a doting grandmother by her oldest child Rhonda Kendrick
