Avril Lavigne sang at the “Volvo for Life” awards ceremony in NY yesterday. Her tummy looked less than flat in a tight top with horizontal black stripes.

The awards honored young people who do extraordinary volunteer work “in the areas of safety, quality of life and environment.” They were hosted by Benjamin Bratt, with performances by Avril Lavigne and the Harlem Gospel Choir.

Lavigne, 21, is rumored to be pregnant. She has been engaged to Sum 41 frontman Deryck Whibley, 25, since June 2005 and owns a home with him in Beverly Hills. She has recently said that she wants to marry Whibley this summer and plans to have children.

Avril Lavigne probably is pregnant as we mentioned yesterday, because now TMZ is reporting that she plans to marry her fiance, Sum 41 frontman Deryck Whibley this summer.

She also is said to wants kids right away, which is celebrity-code for “I’m pregnant.”

Avril is said to be planning a reception with circus performers, comedians and popular rock bands. She’ll probably make a mint off selling the pictures.

Reader Carrie sent these pictures of Avril Lavigne taken on April 1st with what looks like a little baby bump! We first mentioned the rumor that Avril Lavigne was pregnant on March 19th.

Lavigne, 21, has been engaged to Sum 41 frontman Deryck Whibley, 25, since June 2005. The two have owned a home together in Beverly Hills for nearly two years. Lavigne has a small heart-shaped pink tattoo on her right wrist inscribed with the letter “D” and her fiance has been seen out with a wedding band on his left hand.

In a picture of Avril Lavigne and Hilary Duff out partying with their significant others on April 1st, Lavigne is the only one who looks sober.

It could just be a bad picture of Lavigne, but she’s skinny everywhere else and we think she’s pregnant!

Update: Carrie sent another picture from November for comparison. We’re even more convinced. And here’s a high-res version of the bump picture.

The latest celebrity on bump watch is 21 year-old Canadian singer, Avril Lavigne. Lavigne has been engaged to Sum 41 frontman Deryck Whibley, 25, since June 2005. The two have owned a home together in Beverly Hills for nearly two years. Lavigne has a small heart-shaped pink tattoo on her right wrist inscribed with the letter “D”.

Life and Style speculates that Lavigne is pregnant:

At the Paris Fashion Week Swarovski Party on 2/27 Avril placed her hand over her stomach while on the red carpet. (Shown above)

In the latest pictures we have of Lavigne at the Nylon Guys Issue launch party on 3/14 she is wearing two layered shirts and it’s hard to see her tummy. Her fiancee is also hiding his left hand. Lavigne is certainly in a stable relationship, and although she’s young she seems responsible enough to have a child. Only time will tell if she’s actually pregnant.

Samaire Armstrong is set to return to the O.C. this season as Anna. Her character will provide a much-needed challenge for bickering on-screen and real life couple, Summer and Seth.

In a recent interview with gaming site IGN, Armstrong revealed that she thinks she’s tougher than Bilson:

Now that’s a fight we would pay money to see.

The Nylon Magazine Guys Spring 2006 launch party was held last night at the Roosevelt Hotel. Guests included cover boy Adam Brody, his girlfriend Rachel Bilson, and singer Avril Lavigne.

Three more after the jump.
