Miranda Kerr's little boy Flynn is growing up fast, with the cute youngster turning three on Monday.

But with his parents now separated, it was double the celebration for the tyke, who spent the day before enjoying a party with dad Orlando Bloom at his New York home along with a bevy of little pals.

While the Australian supermodel didn't appear to want to intrude on her estranged husband's day with his son, she certainly made sure she looked her absolute best as she dropped him off at the party on Sunday.

The 30-year-old showed off her endless pins in black leather skinny pants and matching ankle boots, which she teamed with a v-neck grey knit top and a knee-length midnight blue woollen trench coat.

Normally one to share her every move on social media, Miranda has kept tight-lipped on how she spent her son's big day with him on Monday, simply posting a photo of a cream-coloured cake with the message 'Happy birthday Flynn' iced on it, complete with three candles.
平时喜欢在社交媒体上分享自己一举一动的米兰达,这次对于周一如何给宝贝儿子过生日则守口如瓶,只是简单的上传了一张上面写有“生日快乐,弗林” 奶油蛋糕的照片,蛋糕上还插了三根蜡烛。

The mother-son day was no doubt spent spoiling her pride and joy with plenty of gifts, love and his favourite organic, gluten-free cake.
