Tuesday was a big birthday for a trio of high profile babies.

Tom Cruise and Katie Holmes welcomed daughter Suri, weighing in at 7 pounds, 7 ounces. "Both mother and daughter are doing well," publicist Arnold Robinson said in a prepared statement. The name Suri has Hebrew origins meaning "princess."

Brooke Shields and husband Chris Henchy welcomed 7 pound daughter, Grier.

Completing the hat trick is my niece Aubrey, the smallest of the trio, at six and a half pounds.

Happy Birthday ladies!

In other baby news, singer Melissa Etheridge and actress Tammy Lynn Michaels are expecting twins this fall. "To answer the obvious question: we used an anonymous donor from a (sperm) bank." The Grammy-winning singer has two children from her relationship with former partner Julie Cypher: daughter Bailey Jean and son Beckett. Cypher had the children through artificial insemination using the sperm of rock legend David Crosby.
