If she hadn’t posted photos of her adorable baby boy on Twitter as proof, it would be hard to believe that Wilde gave birth less than two weeks ago. The actress looked gorgeous in skinny black pants, a white knit top, a blazer with rolled-up sleeves, and black pointed-toe heels. Her minimal makeup revealed a flawless complexion, while her hair looked natural in soft waves. She definitely had that motherly glow!
