TV star Angela Scanlon, who is expecting her first child with her husband Roy Horgan, posted a picture of her delicious looking breakfast with the caption: "Forget flowers, I got a turmeric, black pepper & cardamon latte for V Day. All the stops have been well & truly pulled out".

Dancing with the Stars host Amanda Byram posted an in-depth message to her followers: "Hey kids, listen up!

"Love is not about a day. It’s not about gifts. Valentines Day is a story that’s been made up, and a story that Hallmark have capitalised on. Buying into the story that’s become an expensive circus, is fine - it’s fun and silly and if that’s what makes you happy, then go for it and enjoy!! BUT there’s a danger that people take it too seriously and see it as a statement and a proclamation of how much someone does or does not love them. It is not! 

"It means more if they show you that love in another way on another day. In fact I believe that it’s a total cop out by having one day that you HAVE to say "I love you", when it’s imposed upon you!

"So my message is this.... who cares if he or she does or does not give you a card or chocolates or a kiss today. Material items are NOT an indication of the level of love in your life! Better still, go buy yourself flowers, coffee, chocolate, champagne because loving yourself is WAY more important! 

"PS. I LOVE YOU ❤️ #donttakeitseriously #havefun #whocares #lovecomesinallforms #loveisnotaday"

Reese Witherspoon posted a photo with two of her sons, writing: "Me and my Valentines!"

Even if you hate today use it as an opportunity to tell your mate/Aunty/brother/step dad/mum/second cousin once removed, that you love them ♥️"
