They appear brighter when the air's clearer or when they're higher in the sky. The twinkling's caused by the light being refracted, or bent, by the air - as the air moves around, the star twinkles. It's like looking at something through a heat haze. Unfortunately for astronomers, clear air is often turbulent!

On nights when the lights from the city/nearby towns are not fully lit or are dim, if there are no clouds and other interference to passage of light traveling from the stars, such as clouds, dust cover, moonlight, snow, rain, etc., more of starlight reaches the earth. Hence the stars look brighter than on other days.

the celebrities do look brighter to us in the iciness because iciness air is oftentimes chilly and dry. chilly air can't carry as a lot moisture as warmth air, like in the summer season, therefore generating a more beneficial clearer sky.
