Lottie Tomlinson has been showing off her blossoming baby bump in new snaps. The make-up artist, who recently announced she was pregnant with her first child, took to Instagram to reveal her growing bump in a mirror selfie alongside former tennis star boyfriend, Lewis Burton. The 23 year old and younger sister of One Direction star Louis Tomlinson was positively glowing in the snap, wearing a small lilac bikini to accentuate her bump and her hair in loose waves.
