And the latest celebrity to join in is actor Mark Wahlberg.
The 48-year-old posted a throwback snap to Instagram on Wednesday of himself with wife Rhea Durham at the start of their relationship in 2001.
In the sweet photo, Wahlberg is seen planting a kiss on the side of Durham's head as he poses with one arm around her shoulders.
When they met, she was a successful model and he had a bona fide Hollywood acting career with starring roles in Boogie Nights, Three Kings and The Perfect Storm.
They tied the knot in 2009 and they share four children together - Ella Rae, born in 2003, Michael born in 2006, Brendan Joseph born in 2008 and Grace Margaret born in 2010.
Meanwhile, Wahlberg has been sharing some insights into his family life during the coronavirus lockdown.
A week ago, he shared funny video of his daughter Grace, 10, doing his nails and makeup.
He playfully teased her as she set about giving him the full glam treatment in the family kitchen.
'15 days into quarantine now, I'm getting pedicure with manicures and apparently a full make-up,' Wahlberg explained to his social media followers in the Instagram clip.
'She's got her whole kit there, and yeah, this is what's happening right now.'
Grace giggled a lot, sharing: 'I'm doing horrible makeup.
'I thought you said you were good at makeup?' her famous dad responded. 'Alright, that's enough!'
