Pregnant Jessica Simpson and husband Eric Johnson attend sister Ashlee's gig in LA.

She told her Instagram fans on Friday how cupping has helped her find relief from her extremely swollen feet due to the pregnancy. 

And following her post, Jessica Simpson, 38, was pictured enjoying a night out with husband Eric Johnson,39, as they watched her sister Ashlee and brother-in-law Evan Ross perform at The Roxy in LA.

The American singer, who is gearing up to welcome her third child in the coming days, donned a chic long-sleeved black maxi dress for the concert, which saw iconic diva Diana Ross also in attendance. 

She combated the chillier Los Angeles temperatures with a faux fur stole, which she wrapped around her. 

Jessica added a pop of colour to her muted ensemble in the form of a mixed print bag, which boasted both leopard print and ethnic embroidery. 

The heavily-pregnant star styled her waist-length locks into a tousled wave and sported a glamorous beauty look. 

Following her style lead, former football player Eric wore black jeans, shirt and trainers as they left the venue.
