Man of style! John Stamos bundles up in plaid shirt as he steps out in LA... after reuniting with ER co-stars

John Stamos is simply having a wonderful Christmastime.

The 54-year-old was snapped Saturday taking a walk through a park in Sherman Oaks, California, clad in a red-and-blue plaid shirt, khaki pants and white sneakers. 

He rounded out the casual get-up with a paperboy cap and tinted glasses, sporting a bit of scuff.

Stamos, who played Tony Gates on the show ER from 2005 until 2009, shared a shot with his former co-stars on the NBC medical drama - Linda Cardellini, Scott Grimes, Maura Tierney and Goran Visnjic - on Instagram earlier this week, as they visited his home.

'My #ER cast came to my house for a visit,' he wrote along a shot of the five posed together. 'We took a pic behind our old County General doors,' showing a door which read, 'County General Hospital Public Entrance.'

The actor noted in parenthesis, 'I keep everything,' alongside the festive posting.

Stamos was also pictured as he visited an actual hospital Friday - Memorial Care Miller Children’s & Women’s Hospital in Long Beach, California, not far from where he grew up in Cypress - as he spread well-wishes and provided cupcakes to patients and staff at the facility.

The entertainer was joined by his co-star in Grandfathered Josh Peck, where they re-enacted a scene from the show Grey's Anatomy.

The Full House wrote on Instagram: 'Josh and I making our annual @sprinklescupcakes run at @millerchildrens hospital. We do a scene from #Greysanatomy w/ super cool @carterjhall. Thank you @sprinklescupcakes (I play Meredith) @shuapeck.'

It's been a whirlwind holiday season for the veteran actor, who earlier this month told People that he and fiancee Caitlin McHugh, 31, are going to have a child next year.

'We have the same morals and the same values, that all clicked nicely,' he told the publication. 'So we said, "Oh, well, maybe we should have a family."'
