Rob Kardashian celebrated his one year anniversary with fiancée Blac Chyna with a sweet video.

The 'Keeping Up With the Kardashians' star - who proposed to the 28-year-old model in April 2016 after dating for four months - has taken to social media to share a montage of the couple together, which was originally created by the Instagram account @BlacChynaArmy.

The footage features clips of the pair kissing, cuddling up to one another, Blac stroking Rob's hair whilst he lays in her lap, as well as the couple dancing together, whilst DJ Khaled and Chris Brown's 2015 track 'Hold You Down' played over the top.

The 29-year-old sock designer captioned the heartfelt post: ''1 year down lol woohoooooo happy anniversary babbbbbbiiiiiiiieeeeeee (sic).''

However, the brunette beauty - whose full name is Angela Renée White - has yet to return the kind-hearted gesture.

Meanwhile, Chyna - who has two-month-old daughter Dream with Rob, and four-year-old King Cairo with her former partner Tyga - has dropped an impressive 34 pounds in weight since giving birth to her second child in November last year.

The 'Rob & Chyna' star announced the news of her weight loss on Snapchat, as she shared a picture of her new size on the scales.

She captioned the upload: ''From 192.2 to 158.2.''

And Chyna has insisted breastfeeding has helped her shed the body mass.

Speaking previously, she said: ''I've been carrying a baby for 10 months, so I'm ready to hang out. It's not really scary to be away from Dream, because I have tons of help and I'm not that far. If I was in Paris of New York I would feel super uncomfortable right now.

''I'm just really breastfeeding because you have to wait six weeks until you work out. And I just started hiking with Rob so we're back on our health tip, and I'm drinking a ton of water.''
