Angela Kinsey ("The Office") plans to venture out this weekend and perform at the I.O. West Improv Festival Saturday night, she wrote in a blog entry on Myspace.com

This will be Kinsey's first public appearance since giving birth to her first child, Isabel Ruby Lieberstein, on May 3.

"I definitely do not feel red carpet ready. The ol' body has not gotten back to normal but hopefully I can find some dress that hides what I need hiding," she said.

She will be performing in The Armando Show with "Office" co-stars Oscar and Creed. She will also attend the TV Land Awards with "several members of the cast" on Sunday, she said.

Kinsey also thanked fans for the all the nice messages they've sent since the birth of her baby.

"Your support when it comes to my career and my life are so appreciated," she said.

She added, "And I can't wait to tell you all about little Isabel! She is amazing."
