One is soft in the middle, a hit with mums everywhere and rather tasty...
And the other one is a Cadbury's Creme Egg.
Gary Barlow is turning a half century old this year, and he's sharing the milestone with one of Cadbury's best treats.
The event, dubbed by Cadbury as the 'Golden Goobilee', has been marked with a sweet serenade by the Take That hitmaker.
Dressed head to toe in gold, Gary - who has penned such bangers as Back for Good, Love Ain't Here Anymore and A Million Love Songs - appears to be having the Greatest Day of his life as he serenades an egg in a playful video performance of "Happy Birthday to Goo".
Gary said: “ Turning 50 is a landmark moment in everyone’s life and I am so excited that I share my special day with such an important British icon, my favourite chocolate gooey egg!
"It has been my honour to pen this new and improved version of Happy Birthday to You, and kick off the Golden Goobilee celebrations in style."
To continue the Goobilee celebrations, there's a competition to receive a personalised birthday message from Gary himself over on his official Twitter page.
All you need to do to be in with the chance of winning is to comment below Gary's tweet, using the hashtag #CremeEggGoldenGoobilee. You'll also need to follow @CadburyUK.
Cadbury says there'll be five personalised messages from Gary to birthday winners, and a total of 50 Cadbury Creme Eggs (five packs) given away too.
That ought to sweeten the sting if you don't win the main prize.
If you love Creme Eggs, then keep your eyes peeled for special Golden Creme Eggs that are hidden in stores across the UK. Find one and you'll win up to £5,000.
They're not Back For Goo-d though. You only have up until easter to get one.
