Khloé Kardashian has unleashed a wave of speculation that she is expecting a baby after sharing a very telling photograph.

The youngest Kardashian sister has been on the receiving end of well-wishes after posting an image that fans of the reality star have interpreted as a pregnancy announcement. Khloé, who is celebrating her 33rd birthday today, took to Snapchat to share several photographs of her birthday celebration, but one in particular has caught the attention of her followers. Just seconds after she shared the image of herself and her basketball star boyfriend Tristan Thomson, marked "Dad + Mom", Khloé's fans filled the star's social networks with congratulatory messages. Others have dismissed the 'pregnancy announcement' after the socialite tweeted about feeling hungover: [caption id="attachment_269575" align="aligncenter" width="563"] Image: Khloé Kardashian/Twitter[/caption] Further rumours circulated that Khloé might have some different news to announce, after eagle-eyed fans spotted that she was also sporting a stunning diamond ring on her left-hand during her surprise party.
