Celeb Birthdays: April 4

Resalutations, dear readers! Thank God, Jupiter, Ganesha, et al., Katie Holmes did not unleash little L. Ronette on the world while I was bereft of Internet access. I shall now resume regularly scheduled updates. Also, henceforth please check out my new daily horoscope column at formemagazine.com!

The most mature and sophisticated member of her family by a country mile, Miss Jamie Lynn Spears, celebrates her 15th birthday today. See Jamie Lynn Spears's astrological chart (Astrotheme, no birth time)

Oscar nominee, new dad and all-around sickeningly-perfect-life-having Heath Ledger turns 27 today. Check out our astrological analysis of his Best Actor nod (including a link to his birth chart).

Natasha Lyonne is 27 and by all appearances well on her way to being a full-on train wreck. Which is really too bad, because she was a cool actress back in the day. That Mars-Mercury conjunction in Pisces trining Uranus in water signs might cause some erratic behavior driven by addiction. See Natasha Lyonne's astrological chart (Astrotheme, no birth time)

No, of course David Blaine does not qualify as a legitimate celebrity, but I decided to note his 33rd birthday in order that you might behold his Sun-Venus conjunction in Aries trining Neptune and observe how in love with himself he is.

Fabulous Philly R&B diva Jill Scott is 34.

The Facts of Life's butchie Jo, Nancy McKeon, turns 40. See Nancy McKeon's astrological chart (Astrotheme, no birth time)

At 41, perhaps a mellowed Robert Downey Jr. has some sage words for young Natasha Lyonne. That Mars-Uranus conjunction in Virgo inconjuncting his Sun-Venus cannot have been easy to work through. See Robert Downey Jr.'s astrological chart (Astrotheme, no birth time)

Words fail to express how hilarious David Cross is, and how it saddens me that Arrested Development is no more. But let us not think of it -- happy 42nd birthday! See David Cross's astrological chart (Astrotheme, no birth time)

Endearingly cheeky British comic Graham Norton is 43.

Upon reflection, I've really never been into any of the shows in 50-yar-old David E. Kelley's oeuvre. See David E. Kelley's astrological chart (Astrotheme, no birth time)

Actress Christine Lahti has been in a million things at 56... just don't ask me to name them. See Christine Lahti's astrological chart (Astrotheme, no birth time)

There is certainly something iconic about Craig T. Nelson, who turns 62 today... just don't ask me to pinpoint it.
