Tristan Thompson thinks his girlfriend Khloe Kardashian looks ''better'' now she's pregnant.

The 26-year-old NBA star has thanked the 'Keeping Up With the Kardashians' star - who announced her pregnancy on Wednesday (20.12.17) night - for ''allowing'' him to be part of her life and contributing to the little ''angel'' they've created together, before reassuring her that her burgeoning baby bump suits her and that he'll always be grateful for meeting her.

Writing in response to her baby announcement on Instagram, he said: ''My love, thank you for [allowing] me to be a part of your journey in life and allowing to share this moment with you this is something [I'll] always cherish. Girl you look better now.''

He then added: ''My love, Thank you for allowing me to be apart [sic] of your journey and entering your life that day at the bel air hotel. One of the best moments of my life.

''I'm soo happy to be on this journey together with you and creating this angel from the man above. Everyday [sic] I give thanks to him for bringing us together. I love you soo much and I know our little angel feels the love we share together and will know that mommy and daddy loves them unconditional and forever and ever amen (sic)''

The 33-year-old reality star admitted in her Instagram post that having a baby was her ''greatest dream''.

She wrote alongside a photograph of belly with her and Tristan's hands over it, she wrote: ''My greatest dream realized! We are having a baby! I had been waiting and wondering but God had a plan all along. He knew what He was doing. I simply had to trust in Him and be patient. I still at times can't believe that our love created life! Tristan, thank you for loving me the way that you do! Thank you for treating me like a Queen! Thank you for making me feel beautiful at all stages! Tristan, most of all, Thank you for making me a MOMMY!!! You have made this experience even more magical than I could have envisioned! I will never forget how wonderful you've been to me during this time! Thank you for making me so happy my love! (sic)''

Khloe - who is yet to confirm the gender of her baby - has been dating Tristan for 14 months - a year after she divorced her husband Lamar Odom.

Meanwhile, Tristan has 12-month-old son Prince with his ex-girlfriend Jordan Craig.
