Here's something that's making us smile.
A few hours ago, the 26-year-old songstress hopped on the social media site to send a message to her supportive fans.
"Thank you for all the flowers and lovely messages everybody," Lily wrote. "Very touching indeed. Nuff luv x x."
The last time the "Smile" singer tweeted was on Nov. 25, the day she and husband Sam Cooper reportedly welcomed their daughter, simply writing, "Totes Amaze."
Now, if we can just get a glimpse of the little bundle of joy, that'll really get us grinning.
