The last season of their hit Bravo program ended with a main castmember calling it quits after nearly a decade on air.

But Kyle Richards and Teddi Mellencamp didn't seem to care too much about the drama as they began filming season 10 of Real Housewives of Beverly Hills in Los Angeles on Thursday.

Kyle, 50, and Teddi, 38, were all-smiles as they dined al fresco at the trendy Italian eatery Il Tramezzino off of Ventura Boulevard in Studio City, California.

Kyle looked sensational in a flirty white blouse covered in delicate red flowers and green stems.

She kept things casual as she slipped into a pair of light wash denim jeans for lunch at the Italian restaurant.

Her raven-hued hair was parted down the middle and worn straight with tendrils resting below her shoulders.

Teddi flaunted her muscular biceps wearing a strappy cream-colored tank top paired with gold bangles and a matching watch.

Her signature platinum blonde tresses were worn loosely curled and she had on hints of natural makeup to highlight her features.

Kyle and Teddy were jumping back into the swing of things after a tumultuous season of the reality show where veteran star Lisa Vanderpump decided to hang up her housewife hat.

And Vanderpump might be the least of Kyle's worries as she reportedly urged her sister Kim to return to treatment after weeks of a 'downward spiral.'

A source told Us Weekly last week that Kim's children 'are concerned' about her well-being and believe she needs to seek professional help once again.

'Kyle became aware that Kim was struggling in recent weeks and got extremely concerned based on what she was hearing,' an insider said. 'It's going to be an ongoing conversation, but the good news is that Kim is being extremely receptive to Kyle, recognizing she is coming from a place of love. Kyle isn't giving up and is trying again to get Kim to agree. It's more for mental health than sobriety issues.'

Kim's struggle with alcohol dependency was first revealed on season one in 2011, and she's since been to rehab, relapsed and was arrested twice in 2015.
