Lori Loughlin seems ageless as one of the most cherished and hard-working stars in television. All the years in the business have built some strong relationships between the veteran actress and many costars who have shared scenes with her for more than 30 years. John Stamos, still loved as “Uncle Jesse” on “Full House” and the “Fuller House” continuing family sitcom clearly couldn't let Lori Loughlin's birthday this past Saturday (July 28) go by without a special remembrance, and the actor marked the milestone with a picture and heartfelt words that spanned the years and proved the love and friendship that has stayed steadfast off-screen between the on-screen partners.

The warm and fuzzy exchange was reported July 29 by TODAY and numerous other entertainment news sources.

Not just a number

“Been Jesse to your Rebecca for 30 years,” John Stamos began in his Instagram message.

“30 more, and that's it!” the star lovingly teased before being serious about his next comment that “I don't for one-second take for granted your talent, your heart, and most importantly, our friendship.” Stamos simply topped his genuine remarks with “Happy birthday. Lori! XO”

A tender photo of the friends accompanied the caption, depicting Lori Loughlin and John Stamos on a boat sharing a lovely, sunny day at sea. The dimples and smiles are beaming between the two, and it seems that even then, they could share anything with each other. This is Loughlin’s 54th birthday, which means that for a few weeks, Lori and John will be the same age until his 55th birthday in August. Lori was always the steady and sensitive grounding force as Rebecca to Jesse's wild and carefree antics as a rock 'n roller with a day job and his famous “Have mercy!” tag phrase.

Loughlin shared a photo later with herself, Stamos, Jodie Sweetin, and Candace Cameron Bure together in a “Fuller House” TV family moment, captioned with “So much love for this group!” She replied to Stamos by saying that she was happy to have "shared this journey together."

The years have certainly been kind to Lori Loughlin, a mom to daughters, Isabella Rose and Olivia Jade. The actress has also been featured in infomercials for beauty products [VIDEO], but her age-defying beauty obviously derives from the soul and spirit beyond any serum from a bottle. As if one series in long-running syndication and one on subscription TV is not enough to keep the working mom busy, she is already at work with her “When Calls the Heart” castmates in completing the sixth season of the Hallmark drama, which premieres in 2019. A subscription-based video-on-demand series [VIDEO], “When Hope Calls,” will spinoff from the original early in the new year as well, and it would not be a surprise to see Lori Loughlin make a guest appearance or two.

Birthdays and babies are reasons for community celebrations in the community of Hope Valley, and Lori Loughlin has plenty of reason to be overjoyed in real life and on-screen. Her “When Calls the Heart” character, Abigail Stanton, will surely be there beside Elizabeth Thornton (Erin Krakow) as she gives birth to her child in the new season, and when she held John Stamos’ infant son, Billy, born in April to the actor and his wife, Caitlin McHugh, in April, her words for that moment were “I'm in love.”

Not out of character

Fortunately for Lori Loughlin and John Stamos, as well as their fans, the passions of their real lives and their on-screen characters are not so far apart. When Stamos served as host for “A Capitol Fourth [VIDEO]” on Independence Day, as part of the PBS network special, he became emotional speaking to his baby son and his wife, sitting on the front row, as he spoke of the sacrifice and honor of living in America. Later, he showed off his musicianship with The Beach Boys, and his rock 'n roll chops were still in fine form. Whether on TVLand in "Full House" past episodes, on “Fuller House” or “When Calls the Heart,” Lori Loughlin exemplifies the best of a woman's strength, wisdom, and empathy, and based on her birthday responses, many, many friends appreciate her.
