September 17, 2013 - 12:18 BST hellomagazine.com Hilara Baldwin shows off svelte post-baby figure one month after birth to baby girl Carmen Hilaria Baldwin gave birth to her baby girl a little more than a month ago, and she is already showing off a svelte post-baby figure.Alec Baldwin's yoga instructor wife, 29, who has a striking yoga pose as one of her Twitter profile pictures, is clearly determined to get back into shape after having her baby, who the couple have named Carmen. "First class back @soulcycle post baby... Feels so good!" she tweeted on Sunday. The following day she was spotted arm-in-arm with her 30 Rock actor husband at NBC's 2013 Fall Launch Party in New York. The new mum was stunning in a black sequin-embellished dress that was nipped in at the waist and black stiletto heels. Just days earlier, she was pretty in pink at New York Fashion Week, wearing a gorgeous patterned dress with beige sandals and subtle make-up accentuating her natural glow. Hilaria welcomed her first child at the Mount Sinai Hospital in New York on 23 August, and proudly took to Twitter to share the news. "We are overjoyed to announce the birth of our daughter Carmen Gabriela. She is absolutely perfect. @ABFalecbaldwin @IrelandBBaldwin," she wrote. They have since spoken to HELLO! about their new arrival. "From 7am to 7pm she's a great sleeper," Alec said in an exclusive interview to introduce his little girl. "At night she says, ‘Let's have a conference." But the proud new parents are more than happy to forgo sleep. "Last night we were sitting there, and you realise, I'm not going to have this moment again. I just want to enjoy every moment," he said. Carmen is Alec's second child – he is also a father to 17-year-old Ireland from his marriage to Kim Basinger. The happy couple announced their pregnancy news in February, eight months after they were married in a romantic New York ceremony held at St Patrick's Old Cathedral on 30 June.
