Annie Leibovitz is an American portrait photographer, most famous for her work with Rolling Stone in the 70's and Vanity Fair in the 80's till the present. She has photographed some of the most recognised magazine covers of the last 30 years. She was involved for many years with the feminist and writer Susan Sontag, but their relationship was only made public after Sontag's death in 2004.

Sadly these days Leibovitz is often in the news for her financial woes, and yesterday faced new accusations of balking at bills, less than a month after she struck a deal intended to fix her money problems.

Here's a selection of some of her most famous photos:

John Lennon and Yoko Ono for the Jan. 22, 1981 Rolling Stone cover, shot the day of Lennon's death

Demi Moore pregnant and nude (Aug 1991)

Jane Lynch is an out lesbian and actress whose career first took off in the movie Best In Show. She is now up in the pop culture stratosphere with her portrayal of conniving cheerleading coach Sue Sylvester in the hit show Glee.

Jane is engaged to be married to her partner, Dr Lara Embry. Here's a cute video they released on Saturday promoting the National Center for Lesbian Rights anniversary celebration:

It was announced last week that Jane would receive the 14th Annual Achievement Award from OutFest. "As an actor, comedienne and longtime activist for gay rights issues, Jane has had a profound impact on both mainstream and LGBT audiences," said Kirsten Schaffer, Executive Director of the L.A. based organisation.

Jane is just fabulous in anything she appears in, from The L Word to The 40-Year Old Virgin to Julie & Julia, or hilarious web spoofs with a serious message such as this one:

Yay Jane! We love you!

Tammy Baldwin is an American politician, and has been a Democratic member of the United States House of Representatives since 1999, representing Wisconsin's 2nd congressional district.

Tammy was the first ever openly gay non-incumbent to be elected to the House of Representatives in the United States, and is is one of three openly gay members of Congress. Her partner is Lauren Azar.

We salute you Tammy, for being a trailblazing lesbian and a fighter for progressive values in that harshest of battlegrounds, the US Congress.

Heather Cassils has recently shot to fame as the butch bodybuilder who got to lay some love on Lady Gaga in the ladies' prisonyard sequence in Gaga's Telephone video. There's no doubt that her muscled appearance added a whole lot of queerness to the clip, which has now been seen by over a billion viewers. Heather's also a very interesting person in her own right, working as a personal trainer and a performance artist, dealing with complex issues about gender and body shapes.

In an interview today with AfterEllen.com, Heather declared that she was not a lesbian because she felt like a man inside and preferred to date straight women:

One thing for certain is that I am not a lesbian. Not that there is anything wrong with lesbians, lots of my friends are lesbians, but I never have felt like a lesbian.
- Heather Cassils

Our world is a much richer place for having non-lesbians like you in it, Heather, in it, so we bequeath you the honorary lesbian of the day.

For more Heather, read her interview with Out.com, or check out her bodybuilding and performance art sites.

Chai Feldblum is a gay and disability activist who also happens to be a Law Professor at Georgetown University, Washington. Oh, and an out lesbian. Today President Obama appointed her to one of the seats on the five-member U.S. Equal Employment Opportunity Commission, in what is known as a "recess appointment", after her appointment was blocked by Republicans in the Senate.

I don't understand American politics but I can see that this is one brilliant and hard working lesbian and we're proud to have her on the team.

Annise Parker was today elected Mayor of Houston, Texas, the fourth largest city in the United States. She will be the first openly gay person to lead a major U.S. city. Parker began her political career in the 1980's as an advocate for gay rights. She has been with her partner, Kathy Hubbard, for 19 years and they have three adopted children.

Tonight the voters of Houston have opened the door to history. I acknowledge that. I embrace that. I know what this win means to many of us who never thought we could achieve high office.
-Annise Parker

Yesterday Mary Glasspool was elected the first lesbian and second openly gay bishop in the Anglican church. Her election, in a Los Angeles Episcopal diocese, will have serious consequences for the divided Anglican fellowship, as the Episcopal church supports gay and lesbian bishops and other international Anglican churches do not. A majority of Episcopal dioceses across the country must still confirm the election before she is formally appointed.

Glasspool has said that she had an intense struggle with her sexuality in college, but came to reconcile it with her calling to become a priest. She llives with her partner of 21 years, Becki Sander. She said in a statement after the vote:

Any group of people who have been oppressed because of any one, isolated aspect of their persons yearns for justice and equal rights.

The inaugural lesbian of the day, who has inspired me to start this blog, is Meredith Baxter, former star of "Family Ties". Meredith bravely came out on national television today, with these words:

This is a political act. If anybody knows someone who is gay or lesbian... they're less likely to vote against them, to take away their rights. So if you knew me before, and you cared about me before, I'm the same woman... I can be that lesbian you know now.
