The iconic onscreen couple looked as cozy as ever as they posed on a ladder at an Old Navy store in Los Angeles.

At one point Perry even nuzzled his former costar's neck.

Jennie, 40, recently revealed that 45-year-old Perry has helped her through her divorce from Twilight actor Peter Facinelli, her husband of 11 years.

'Luke has been one of my friends who I can call and talk about stuff and has been through something himself,' the mother-of-three said in this week's In Touch.

And Luke must have an insight into her grief, having divorced his wife of a decade Minnie Sharp nine years ago. They share joint custody of their two children Jack and Sophie.

The smiling actress told US Weekly at the three-day event that she is currently writing a sitcom with Perry.

'We want to work together again because we really love each other and it would be nice to spend time together working,' Garth said.

Perry, whom Garth calls 'one of my best friends,' was handsomely rumpled as always in a striped button-up, loose blue jeans, and black canvas sneakers.

Meanwhile, Jennie looked youthful as ever in her kelly-green top with kimono sleeves, black trousers, and black strappy heels while reminiscing with excited fans at the Beverly Boulevard store.

The Old Navy event, which ends Sunday, also offers fans a free pair of jeans and a chance to meet 90210 veteran Gabrielle Carteris as well as live music, DJ, a photo booth, and fun giveaways.

'It was very easy,' Perry told People Magazine of working with Garth and former co-star Jason Priestley, who shot an Old Navy ad with the two last month.

'It all seemed very familiar... here I am standing on the mark, he’s on the mark, she’s [on the mark]. We all just started laughing.'

Garth is the only cast member to have played her character in Beverly Hills, 90210 and both its spin-offs Melrose Place and 90210, where Kelly grew up to be West Beverly Hills High's guidance counselor and single mother to brooding Dylan's son Sammy.

Today, Jennie posted on Twitter about embarking on a road trip with her three blonde daughters - 15-year-old Luca, nine-year-old Lola, and five-year-old Fiona.

The newly single star just began dating photographer Noah Abrams, 33, who's shot for Rolling Stone, Vanity Fair, Sports Illustrated, and GQ.

After her March split with Facinelli after 17 years as a couple, Jennie noticeably lost weight which she credits to careful diet and lots of exercise.

'I'm just taking care of myself: Eating less, exercising more, drinking a lot of coconut water,' Garth told Us Weekly.

'I eat a lot of Greek yogurt: Greek yogurt in the morning, salads and proteins the rest of the day and maybe a cupcake if I've been a good girl. I don't believe in depriving yourself of things you want.'

The Jennie Garth: A Little Bit Country star just wrapped The Eleventh Hour, a Lifetime movie adaptation of CNN correspondent Nancy Grace's novel.

She'll next appear in another made-for-TV movie called Village People later this year, in which a single, high-powered career woman looks to start a family and ends up taking in the pregnant teenager she was planning to adopt from.

Meanwhile, Perry has several upcoming films, including next year's romantic drama Red Wing with Bill Paxton and Frances Fisher, and the fantasy film Dragon Warriors with James Marsters.
