The 28-year-old took her four-year-old son King Cairo, who she shares with ex-fiance Tyga, to Nickelodeon's annual awards on Saturday (11Mar17), which was hosted by former wrestler John Cena.

Chyna, who recently split from Rob Kardashian after they welcomed daughter Dream in November (16), showed off her post-baby weight loss on the orange carpet in a white shirt and silver trousers, matching her outfit to her son's.

However, she managed to avoid an awkward encounter with another Kardashian ex - Khloe's former husband Lamar Odom - who walked the orange carpet with his two children.

The 37-year-old former basketball star made a surprise appearance at the awards with son Lamar Jr. and daughter Destiny, and walked past Chyna while posing for photos, but the pair did not interact, according to People.com.

Chyna's history with the Kardashians goes back to 2014, when she split from rapper Tyga who went on to date Rob's younger sister Kylie Jenner. The new couple caused controversy as Kylie was only 16 at the time, two years below the legal age of consent in California.

Chyna and Rob got together in early 2016, and were engaged by April, and welcomed daughter Dream Renee Kardashian in November. Last month (17), the couple had split after a tumultuous relationship, which included Rob's vitriolic outbursts on social media, and feuds with his famous reality show family.

Khloe and Lamar wed after a whirlwind romance in 2009, but finalised their divorce in December (16) after being separated since 2013. The reality star is now dating 25-year-old Cleveland Cavaliers basketball player Tristan Thompson.
