Kate Beckinsale's daughter Lily paid a sweet tribute to her actress mother as the British star celebrated her birthday on Wednesday (26Jul217).

The teenager, whose father is actor Michael Sheen, shared a cute throwback picture of herself with her mom, taken on a day out over 10 years ago. Lily looked considerably younger, and acknowledged that her mother was at that point the coolest person in the snap.

"happy birthday mama!!!! most amazing person i've ever been birthed by and ever hope to be," the 18-year-old wrote. "i wish we still styled out like this tho... i'm serving toothless bohemian looks age 6 and you're absolutely stunting with a pair of red bottoms and the classiq capri leggings/wispy skirt combo. you're an icon and i adore you!!!!!!! (sic).”

She ended the message with half a dozen heart emojis.

Kate responded with a memory of her own on the picture noting "this was the exact time you got catfished on eBay for a tamagotchi my god I couldn't love you more." To which Lily replied it was the "worst summer of all time".

The Underworld star later posted a picture of herself with rock icon Mick Jagger, with whom she shares her 26 July birthday. The Rolling Stones star turned 74 on the same day.

"I get to share my birthday with some AMAZING people. My mother (actress Judy Loe) shares hers with the first ever packet of frozen fishfingers and has always felt dubious about it," Kate captioned the post as she thanked fans "for all the lovely birthday messages AND Happy shared Birthday to @mickjagger. It sucks not to be the coolest one but I'm also glad I'm not a fishstick."

In pictures obtained by Daily Mail Online, bouquets and boxes of flowers were seen being delivered to actress's Los Angeles home on Wednesday afternoon.
