Grammy Award-winning singer/songwriter Melissa Etheridge and her actress girlfriend Tammy Lynn Michaels are set to follow Ellen DeGeneres and Portia De Rossi up the aisle.

Etheridge says, "We have four children and we're trying to find the right time (to wed)."

DeGeneres and DeRossi became the first high-profile lesbian couple to exchange vows when they wed in August (08).

Same sex marriage was declared legal in California in May (08), but critics of the new legislation are attempting to overturn it with a statewide vote in November (08). (c) WENN
